actually these videos are helping me along with my college experience. I struggled with math as a young in and became very discouraged about anything to do with numbers. However, this time around Im enjoying the pleasures of learning math chapter by chapter.
Todays generation are so lucky because of fast technology they can search for answers quickly online.. Our previous generation, we struggle a lot esp. In rural areas which textbooks are limited in some schools. What we had experience more were had fun games without gadget.
Probably has to scream if the class is noisy or playing on their cell phones. It is a different dynamic in a classroom. If your teacher had the opportunity to tutor you individually, you'd benefit more.
That's common also, however you remember it is fine. Just remember brackets means all grouping symbols and always reapply the order of operations when inside.
I absolutely love your instruction I love how you reinforce every rule on each question and I’m curious as to know if you do private tutoring for graduate students who need help in this type of math questions? Even if I could pay you hourly on zoom I would really need the help before I take my Praxis test please let me know, thank you so much for this video, Michelle
I don't do any private tutoring, but you can self study with my free website: greenemath.com You can start at the most basic pre-algebra and go as far as you need. There's written lessons, practice tests, and quizzes. Also there is a practice test section that will generate as many tests until you have mastered the given topic. The site is funded by ads, but you can turn them off in the menu. Let me know if you have any questions.
@@Greenemath Oh darn, I was looking for a couple zoom sessions because I am taking the Praxis 5003 and I already am a teacher but thank you so much for responding and thank you for the videos! You are an excellent math teacher! Kind regards, Michelle
It's inside of an absolute value operation. Those vertical bars around the -15 are telling you to take the absolute value: |-15|. The problem is 3 x | - 15| + 10 = 3 x 15 + 10 = 45 + 10 = 55. The absolute value operation makes things non-negative. So a negative 15 becomes a positive 15.
I get it, but not with fractions. I’m such a slow person. Idk if I’m dyslexic or that I’m just dumb in reality, but I’m currently an 8th grader who can’t seem to understand the order of operations along with fractions. My math tutor doesn’t just directly give you the problem. They make you narrow it down many times. They do things like: (+3)x-8-(+3/8x1 1/2 + (+4/9)= and weird stuff like that , all those math symbols gets my mind confused and then I feel like giving up.
Most people don't get math right away, so don't feel bad. The best thing to do is lots of practice. It's just like anything else, if you practice, you will get better over time. :)
8 - (-2) x (-7 + 3) Do what's inside of parentheses first: -7 + 3 = -4 Replace this 8 - (-2) x -4 Next, do the multiplication: -2 x -4 = 8 Replace this: 8 - 8 Lastly, perform the subtraction: 8 - 8 = 0 So zero is our final answer.
I still get mixed up with when you have to turn adding to subtracting (or the other way around) like -2 + 6 do I add or subtract? I’ve been studying for 2 hours and I feel like still haven’t learned anything :(
Unfortunately, it just takes a lot of practice. If you are working with integers, I would always add. So this means for a subtraction problem, you would do addition of the opposite. -2 + 6 = 4 because you would subtract 6 - 2 = 4 and keep the sign from the number with the larger absolute value. I would suggest watching videos on just adding integers and subtracting integers. When you feel comfortable, then move back into the order of operations.

🤔 Hello. There is another method to help you understand this problem. Draw a number line with zero at the mid point. Negative numbers appear on one side, positive numbers on the other side. Either direction is valid. -10. -9. -8. -7. -6. -5. -4. -3. -2. -1. 0. +1. +2. +3. +4. +5. +6. +7. +8. +9. +10 Now find -2. Then move in the positive direction 6 steps. You arrive at +4. That is your answer. I hope this is helpful for you.
You should first watch the videos on adding integers and subtracting integers. adding integers: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6NQXbtcWntY.html subtracting integers: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oJeR8viOcsM.html Long story short if you don't want to watch the videos. Adding Two Integers with a Common Sign: Basically the sign stays the same and you just add the absolute values. -5 + (-7) = -12 -2 + (-3) = -5 Adding Two Integers with a Different Sign: Think about both numbers in terms of absolute values. Basically just make the numbers positive. Subtract the smaller away from the larger. This gives you your answer in terms of absolute value. Use the sign of the original number with the larger absolute value. -17 + 11 Since -17 has a larger absolute value, the answer will be negative. So now all I have to do is subtract 17 - 11 = 6 -17 + 11 = -6 14 + (-8) Since 14 has a larger absolute value, the answer will be positive. So now all I have to do is subtract 14 - 8 = 6 14 + (-8) = 6 Hope this helps, if it doesn't drop the specific examples from your homework and I'll help you solve them.
the |-15| means to take the absolute value. The absolute value of a number is always non-negative, so it gives us 15. Then the "x" means multiplication, so 3 x 15 is 3 times 15.
You are thinking of the rules for multiplication and division with integers. If the signs are different, your answer is negative and if the signs are the same, your answer is positive. With addition of integers, we have to think about which sign carries more weight. In this case we have 12 + (-9). If we think about these two numbers without the signs, one is 12 and one is 9, the 12 is larger, so this will carry more weight. This means we will have a positive answer. Another way to think about this is with a bank account. Suppose we have $12 in our account and we subtract away 9. We still have $3 dollars left, which is a positive amount.

Basically use pemdas parenthesis brackets exponents multiply divided add and subtract so it in order and if u see a number like this (-3) do the opposite of the sign that ur doing
Hey I don't know if you'll still respond but the thing where two negatives make positive,two positives make negative,etc... I want to know what specific equation or rule that's called
Are you talking about for multiplication and division of integers? I don't know if there is an official name, I would maybe say it is the sign rules for multiplication and division of integers.
Honestly, most math is confusing at first. It's just something you have to practice with. Let me know if you get stuck on a particular problem and I'll try to help you out.
Wait .. wait, wait. You _don't_ have any parentheses? Except the two that are there? I get that maybe the -9 has nothing to do; but the first (-2)exponent 2? Do we not do that first?
im so sorry but im just pretty slow .. i just dnt get it this kind of problem .. (6 - (-3)) = 9 ??? why ?? i thought 3 is the answer .. can u pls xplain more ?? thank you
When you subtract away a negative number, it is the same as adding a positive. So 6 - (-3) can be thought of as 6 + 3 = 9. Just change the subtraction sign to addition, then change the number being subtracted away to its opposite or you could say just change the sign. So for 5 - (-2) we change the minus to plus and change (-2) to (+2). We can write the problem as 5 + 2 = 7. Hope this helps some, integers can be challenging at first, but once you practice enough it will become second nature :)
GreeneMath.com so u mean sir/ma'am when two negative sign combine will it be positive ?? in any mathematical problem ?? for ex. -10 ÷ -5 = 2 or -2 ?? im so sorry im just pretty slow 😥
The rules will differ based on your scenario. If you are dividing or multiplying, two negatives will give you a positive. In general with multiplication or division, the same sign will give you a positive result.
Don't say that. Just go to the material repeatedly. Sleep with it wake up with it read it continuously do it. It will sink in your head. You will see the patterns nice and slow do not get frustrated. You're not a slow learner you're just not getting it. You have to really soak it up pay attention. Turn off the cell phone go to the library put earphones on really pay attention to it
Absolute value is always positive because it refers to the distance of the number from zero on the number line. "How many spaces from zero is -15?" Distance isn't negative.
I get the lesson completely but my answer is still wrong. I dont know what i did wrong. HELP HELP HELP There's a lot of exponents and division, multiplication and brackets and stuff. IM ONLY GRADE 6
[27÷(-9)] - [3×(-2)] Do the division on the left first: 27 / (-9) = -3 -3 - [3(-2)] Do the multiplication on the right next: 3(-2) = -6 -3 - (-6) Subtract: -3 - (-6) = -3 + 6 = 3
You are thinking of multiplication. If you add two negative numbers, you get a negative number. -3 + (-4) = -7 If you multiply two negative numbers, you get a positive number. (-3)(-4) = 12.
yeah i dont understand how to figure when im supposed to add the equasion or multiply etc like this 4-3x(3-_2)) is that a minus subraction symboy or a neggitaive @@Greenemath
@@Codenamenarc007 The easiest way to think about this is by changing the subtraction to addition of the opposite. Now, the way your wrote the problem is a bit strange. There's an underscore in front of the 2? I'm going to modify your problem slightly: 4 - 3x(3x - 2) So what I would do is write the "-3x" part as + (-3x): 4 + (-3x)(3x - 2) You can also write the (-2) as + (-2): 4 + (-3x)(3x + (-2)) This seems like a lot of work, but if you are struggling with signs, it can help. Eventually, you will get comfortable and you won't have to do this. Now you can use the distributive property and distribute the (-3x) to each term inside of the parentheses. 4 + (-3x)(3x) + (-3x)(-2) 4 + (-9x^2) + (6x) -9x^2 + 6x + 4 So to keep things simple for you, I would change your subtraction to addition of the opposite. This will help you keep your signs straight. If you want to retype that problem, I can go through it. I don't know what the underscore 2 was?
I was searching for these kind of equations I have trouble understanding hard problems because I dont pay attention to the common and easy rules.this is rlly weird I'm not in the grade to learn this I feel stupid
Don't feel stupid. Math is really hard to learn, a lot harder than other subjects. You have to practice enough. Just keep watching the tutorials on RU-vid and work along with the instructors. You will get there! :)
There are different ways to remember it. Most people learn PEMDAS. You just need to understand the correct order, however you decide to remember the order of operations. Good luck with your studies :)
Let's just rewrite this for clarity: 5 x (-6) + 18 - [15 / (-5)] Let's start with the parentheses or in this case the brackets: [15 / -5] = -3 Now we will replace this in our problem: 5 x (-6) + 18 - (-3) = 5 x (-6) + 18 + 3 Nex, we will perform our multiplication: 5 x (-6) = -30 No we will replace this in our problem: -30 + 18 + 3 Now, we can just add: -30 + 18 + 3 = -12 + 3 = -9 5 x (-6) + 18 - [15 / (-5)] = -9
You lost me at the -5. When you explained that -3 -2 was -3- +2. My thought would be to subtract because + and - = - and subtract the difference but you added instead and added a bonus of a negative. This part here Is where I would go wrong on a test.
You can really think about subtracting away a number by adding the opposite of the number. So -3 - 2 = -3 + (-2). Now you can just follow the rules for adding integers with like signs. Since both are negative, just add the absolute values (ignore the signs) and then attach the negative. So we end up with -3 + (-2) = -(3 + 2) = -5. Hope this helps you :)
