5 Math Skills Every Programmer Needs 

Don't let this video scare you off. If you're good at math you'll likely be disappointed in most programming jobs, because it's so rare to encounter anything requiring more than high school math. Source: Professional programmer of 15 years.

Top 5 Maths Skill 1. Combination 2. Logarithm 3. Factorial 4. Exponentials 5. Modulus

"We don't have the luxury to giveup the process just because we don't like one particular thing" true.

The five math skills I need for my job are; addition, subtraction, multiplication, division, and fractions.

Senior Engineer with 8 years experience at a decently sized Australian tech company. I do have an engineering degree but don't consider it a necessity. I don't use these concepts often, but do occasionally. Mod and Exponential are the most useful. I don't really drill people on Log if you can eyeball a loop and explain what's happening and I can follow then that's a question answered well. Encouraging people to make mistakes and learn from them. The most important thing is to be able to think logically and be able to articulate decisions.

Outstanding video and thoughts on what can help a developer! Having not been in a math class in a LONG time, the first two I'm very rusty in, but the last three I understand. If I had thought of what I know already, a lot of coding problems/DSAs would have been easier to approach. Instead, I over complicated things by not really understanding what I was seeing and read. Thank you for this video, it really cleared up some things for me!!! Now, I can use this approach to get better and confident in resolving issues.

This is a brilliant piece of teaching, with one real-life case illustrating five crucial math concepts!

One more concept that is missing is probability. In your exponential backoff example, the true algorithm doesn't exactly back off exponentially but rather picks a random number between 0 and x^N. This ensures that simultaneous clients don't remain synchronized and traffic can get through.

I am doing it. I am getting it every day. Inch by inch. I know that one day it will happen. As long as people like you exist! I will make it possible. Thank you so much. Keep spreading knowledge.

Mathematics is not only good for software engineers but mathematics helps a common man in every field of life. By the way I love to learn new examples and solutions of mathematical problems. Your way of explaining the mathematics importance is very impressive 👍

Finally a crystal clear answer to this question Thank You and Much Appreciated👍

As a mathematician who has always been working in software development, I often find it frustrating, how little Math I'm actually able to use. The recommendations in the video were spot on. Though, aspiring developers should never underestimate the value of a solid theoretical background. If you have an area of interest besides computing, you should go for it and learn to code as a secondary skill. It doesn't matter if it is physics, mathematics, chemistry, economy, electrical engineering, linguistics - even history of art. Computer science is also great, as it provides a lot of insight, you will have a hard time mastering if you just focus on your practical skills.

One of the best videos on the subject matter I think. And you have teaching talent as well.

The way you teaching mathematics concepts, It's great developer can relate concepts while coding. Awesome

Honestly, I think the main point here is that knowledge is more linear than spacial than most think. It means, your scalar level grows as much as you learn, despite the actual content, because all boils down to how mature is your brain to associate problems with a solution. The actual subject is important for a specific need (like answering something fast), but in a long run, who knows when you gonna use it again? So, in the end, always keep learning, despite being engineering or math, physics or other. The more you learn, more evolved is your brain, more capable person you are.

There are some channels I feel proud that Ive subscribed to them.. Power Couple is one of them 👍

Really loved this! Thank you man! ❤️👍

Dude i have watched 2-3 videos on log and time complexity. And this particular topic where we use logarithm to describe time complete. I never understood what it actually meant but you just explained it so simply in a few minutes. Now i need you to teach me DSA man.

This is indeed gold, great job! 👍

One of the best video so far I came across, Thanks for such video.

Such a beautiful information with Powerful delivery awesome man 👌🏻 god bless you for helping all of us. Thanks

i think if you have touched the programming of robots, you may realize there are a lot of maths involved including matrix, calculus, tensors, linear algebra, .. etc. If you work with neural networks, also involved a lot of maths of different areas.

Thank you so much for your videos, you help me a lot to look and move forward with coding!

I love your content, keep uploading in this manner

Your graphical display of exponentials really drives the message home. Great video.

One of the reasons programming is challenging is because an individual must learn and waste time on a lot of things that are never used. Nested loops are a bad practice in real world implementations yet a programmer must be aware of them anyway.

This guy is right! You win my like and I am following now!

This video is spot on! Thank you for sharing it

Time complexity is n*logn since for post increment I++ or post decrement i-- time complexity is n for addition and substraction . In second case it is logn for i*2 similar for division.so there is for loop inside another for loop so we will multiply both time complexities.Hence time complexity becomes n*logn

This was an amazing video!! Thank you man

Thanks a lot This is what i was searching from long time

The beauty of computing is, you can test out the answer by your own by implementing your thought. Also, only a very small number of programmers are needed to focus on algorithm while most of us are just struggling in a chaotic framework world. basically you are expected to follow your manuals (doc) when you want to implement something.

Wow! The way you explained the things 🔥 was great

Motivation , direction , everything in one channel, for free , can not thank you enough for taking time to make these videos

Heyyy!!! This video is amazing, not only because of its great content, but because I come back here whenever I need a skill check. May you please make more of these? Your teaching method is amazing. THANK YOUUU!!!

I like the way you script the video. It has good logic structure and it is easy to follow.

please bring more such videos related to data structures and algorithms explaining the concept...love ya!

Wow! Never seen a simple, short but powerful example covering all the 5 vital skills which are explained very clearly 🙏🙏🙏

So much good stuff crammed into a 9min video!! Maza agya!

Huge thanks for some info m8t, even as a CS student this is often overlooked at

Spent a year learning modular arithmetics and mathematical analysis after watching the video. Thanks! I enjoyed math really

Very well made video; will definitely search more about these concepts on my own. I like your attitude, by the way, I think you'd make a great teacher.

First after finishing the video i felt like i wasted my time since i learned all of these comcepts on extreme levels of difficulty in highschool already. But then realising that i'll actually be using my math skills in programming make me appreciate my highschool a lot more and in turn gave me so much motivation and felt so much better than i was. Thank you, have my sub.

This is awesome and motivating- thank you!

I honestly don’t regret going into Chem E vs being a programmer, after we complete our research, designs/drawings are finalized, we’re going home, the programmers were ALWAYS on the clock during big projects(but they are very important). I do enjoy using math to solve problems, but not in the same way programmers use it.

Just another quality content 😉 and another accreditation from me as to ur previous videos . Love it ✌️

You really helped me to get my target. Keep going💪

Shalom very cold afternoon here in Texas. This is very good. Thank you for sharing this!

OMG!! I just really appreciate your content, video, efforts & knowledge! It is genuinely worth knowing & helpful!! #lotsoflove🇮🇳❤️

These math problems are pretty easy, we used to have to solve a lot of tasks like this when I was a student in high school.☺ I loved these tasks.

This video saved my life! Thank you!

Subscribed. Awesome video. Will go through these concepts

Thank you my friend. I am learning programming in my middle-age. I find programming is real fun, but I also find the maths skills you are discussing are also enjoyable. Even the professor did not explain the concept of exponential to me clearly when I was studying finance, but your video did it.

Another great useful video, thanks 👌

Thank you for this content.

Great applications and lessons on applying math to computation!

Thanks for the video, very informative

Following the way of "learning by doing or start doing after learning the basics" according to you said I made couple of projects but i suddenly realized that i became more of a person who google stuffs than actually understand why we are using a code in a particular scenario , although i understand which type of code to use in solving a particular problem but if someone ask me to solve the problem in a alternative way maybe i would fail to do it ... Can you shed some light on my problem it will be really helpful, i hope u understood my problem 🙏

Excellent video, Thank you!

Very proud to follow you and to watch your videos always there is something new thanks lot

Excellent video explains with simple and effective method Thanks for sharing

Calculus ( even a painter needs it ) + Linear algebra + Statistics & Probabilty + Discrete math. This is what you need. For a start.

This is extremely helpful, Thank you ! 😊

Great video, thanks!

Finally, I have platform where i can use my class 11th and 12th maths. After watching that video I am feeling to good taking science stream at my higher secondary studies.🤩🤩🤩

Thats a bit missleading. For backend guys.. sure. But as FE dev I never used any of the concepts u have noted in your video. The most difficult math I ever had to do was to calculate the final price in the basket after deducing the 20% discount. Counting with percentages is being taught at around 3 or 4 class of math pre-algebra at elementary school.

I didn't know any of this maths right now but i will learn them .. thanks for sharing.

Thank you for making this video.

As all these concepts are covered in schools on secondary level in my country - it’s as obvious requirement as ability to read and write ;)

What a great condensed video!

Loved your video ❤ please put more content like this related to useful math skills in programming.

Sir pls make a Playlist for Data structure and Algorithm...

hi it amazing content can u plz create tutorials on all maths that are required for coding as playlist for learning or can u plz sugest sourse to leanr theem??

It's fun that all this math skills you are talking about in video, in Poland we have mandatory in high school.

You explained very fluently how programming is related to maths very helpful video 🙏🙏🙏

this is the question i asked my mentors but they told we dont need maths ...... Nice video keep going

Having done programming casually since elementary school (I began teaching myself BASIC in second grade!) I can tell you that math is probably the biggest part of programming. Virtually every program-- even the simplest ones-- use variables to some extent, and usually also apply functions to said variables. Unless you're writing a "Hello, world!" program, you're using variables and by extension, basic algebra. If you ask the user for any input at all during a program, you need a variable to store it, be it a numeric value or a text string. And if you want to do anything to that user input besides repeat it back to them, you're going to have to write a mathematical expression that involves the variable that stores said user input. In short, programming IS math.

now i understand the log part in the coding, thanks😁

Great points. I teach STEM and include coding in my math (Calc, Analytic Geo, Linear Algebra, etc) and Astrophysics classes at the high school level. Also, not to be too picky but @7:53 that graph was not an exponential function (it fails the vertical line test)

5 skills: Calculus, Optimization, Probability & Statistics, Numerical analysis, Algorithms

If you make videos like this and teach these methods to the beginners your channel will grow very fast, because people need to learn these topics in easy way

at 3:56 generally in mathematics it is log base 10 because we are dealing with decimal number system in computer science we are generally deal with binary that's why log base 2

Thanks, this was really helpful.

Can you please make a video on current layoffs and what lies ahead , especially for students who are in their final year of college preparing for companies

things to add, from my experience 1. If you are just a web dev, basic math would suffice, maybe an introduction to discrete math, graph theory, and set theory 2. Embedded systems, depending on the task can vary from simple IoT devices to full-blown embedded controllers, which HEAVILY use math (Signal analysis, calculus, (discrete)Laplace transform ) 3. AI, and machine learning programmers, heavily use graph theory and predominantly linear algebra for their optimization algorithm, gradient, and non-gradient-based optimizer. If you want to know the "under the hood" math of AI, you can read engineering design optimization by Joaquim. Although that book does not explicitly say AI ML design, but its knowledge is easily transferable to AI ML design. 4. Robotic, and mechatronic is a combination of DSP, kinematic, and dynamic mechanic 4. Dont ask me about 3d graphic engines, I never touch that subject (with that being said, I usually forgot about fizzbuzz and big O notation)

As a programmer I can say this is a great simple and clear info.

I'm taking Harvard's CS50 beginner programming course and the lecture on Algorithms tripped me up! I was confused about time and space complexity and Big-O Notation. Thank you for making this video. Your clear and concise breakdown using the ruler and for loop helped me understand the concept! My comment translated to emoji: 🥴😵‍💫😵 ... 😮🧐🤓

One word , DISCRETE MATHS

so what would be the answer if the nested loop was j*3 for each iteration?

Great vid!

Excellent brother, I'm always waiting for your upcoming videos!! 🇧🇩

You certainly do not need math for web development, anyone telling you that you need math for web development is a fraud trying to sell you a course, or someone who is just a gatekeeper.

Another way to think about this stuff is to think about the goal in simple words - i.e. we want to reduce load on the server, and assume the server gets weak on each request. It'll automatically lead to these functions.

The example given in this video to use a that algorithm is an edge case. Having a deep understanding of Javascript and building an Next App at large scale company does not need you to be a math bad ass. Yes data structures and algos will help you be a better progarrming. But even then how much bubble sorting does a front-end engineer need to do to optimize the front end?

As a person who was lucky enough to learn these things at school, I’m surprised to find out that this is not a common knowledge. Thanks for trying to make it one.

Even tho I'm good at all these math skills, I still struggle a bit while coding mathematical codes. Math is a must for programmers.

Your technique of teaching is so different...🥰

Never needed to calc nested for loops; but for interviews it might be useful … learning to measure performance and optimisation is more important.

Thank you , I just entered a software engineer boot camp . Im taking MS psychology as well.

2:07 Time complexity : N(√N +1) Sorry if I'm wrong
