(4 + 3) times 2 minus 10 divided by 2 =? A BASIC Math problem MANY will get WRONG! 

Not really

Exactly why I clicked to watch 😂

Buahahahah!! I wasn't gonna say it!

How do you mess up seventh grade math

He is correct, I did it in my head. It's really easy

Thank you! If my guess was wrong I would have watched the video.

The answer is 9.

D is answer

They should have put 2 as a possibility, the most common mistake.

Thank you..he lost me when he began going off into left field with explanations

(4+3)2 - 5 arent equal to 7(2) - 5 [(4+3)2] - 5 is the correct one

You are correct. The answer is 9.

@@mikemcklieve🤭 Wrong! Stay in school! Answer is 9! 🤫

@@ArleneElvin-sy7qi This is like 5th or 6th grade math! You must have flunked math in elementary school! SMH

Me too!

I'm 76 and I didn't know about "pemdas" or "bedmas" until about 4 months ago. I asked my granddaughters about it (they're both engineering students at VPI) and they acknowledged they are familiar with it but find it very obtuse. I was a straight A student in math and an engineering major in college, but I have never run into this way of writing an equation. KISS!

1958 model here, I’ve never heard of this process, even after Algebra I, II, and Geometry. 💙

Me too my teacher didn't emphasize Multiplication and Division are EQUAL operations as are Addition and Division. I messed up thinking you had to multiply first. Took a tutor to show me 🤷🤦

​@@hollyjobitner3285 Born 1952. Did better in the Algebras than Geometry. Word problems always stymied me. My dad used to try and help me with those. You know, two trains going at different times and speeds, etc. How long it takes to reach their destinations. Hated those type math problems.

Yes, there are many professions that don't require understanding of math. Regardless, people benefit from a well rounded education through high school. There have been many very solid studies done regarding the benefits of a well rounded education. Generally, people who have a rounded education are better at many life skills such as general problem solving. I certainly don't think that beyond a first year in college that everyone needs to pursue higher math, but you probably have benefitted far more than you even know by having at least some education in a variety of subject matter, even subjects that you don't see as being directly related to your chosen profession.

I think you might want to review PEMDAS; it's not PEDMAS.

D-9

It's PEMDAS 👍🏽

@@yungsmile7546 Better yet, forget it altogether. Parentheses are the proper way of setting precedence in an expression. Worst of all, PEMDAS is just an American and French crutch. Mathematics is worldwide. In 11th grade our Advanced Math teacher took seven of us - her students - to UC Berkeley to listen to a presentation by Georg Polya. The renowned mathematician spoke and presented for about 40 minutes and never once relied on PEMDAS. It was memorable for more than that. Our teacher had a Karmann Ghia; it would carry four in a pinch. We had three lap-sitters and I was the smallest, scrunched into the rear window hat shelf. Who says math is boring?!.

I am 65 and I was at school in the UK. I was taught BODMAS Brackets Over Divide Multiply Add Subtract. Answer is 9. Many people leave school after not learning what was taught to them. Ignorance is no defence for being wrong. Wrong is always wrong. Conversely in English the rule , "I before E except after C" has stopped being taught in schools now as there are more words that do not follow the rule than does. Forget AI and always insist on Real Intelligence. Take care and have fun.

@@dougbowyer The fact is that BODMAS is not a mathematical rule, it is a convention which I was never taught. I'm 71 by the way. Imagine relying on a convention to be understood when instead you could write the equation in such a form that nobody could misunderstand the order in which you solve it, which is what I did when I wrote "This equation should be written as (4+3)2 - (10÷2) to get the answer 9". To get the answer 2, you write it down as a fraction as (4 +3)2 -10 over 2 in which you calculate the top line (the numerator) first and then divide by 2, the denominator. There is no need for BODMAS as all anyone needs to do is simply to write clear equations in which you work in a sensible way from left to right in just the same way as you read my message to you and that, I suggest, is using real intelligence to ensure that everyone tackles the equation in the intended order and gets the same answer. Relying on a knowledge of a convention to determine the order of solving it is clearly not a good way and this video proves that point. Many people have produced different answers and this shows the deficiencies of BODMAS. You too take care and have fun.

I was taught exactly like you. The question should have been written like this: (4+3)2 - 10/2

An add " = x " to your equation to make it totally unambigous.

I agree. My answer was 2.​@dougbowyer

This was a sh!t video because an imprecise definition of a calculation is bound to cause errors, and possibly injury or death if used in engineering. Using this as an definition of a calculation is the very worst kind of example to set. It is bordering on negligence for a supposed maths question to be so badly expressed

Wow. Thank you. I needed that refresher

So this is an engineering problem?​@@edeledeledel5490

I was so hopeless at maths that I was permitted to skip the final exams - this, after my father (who was also scared of the subject) trying to teach me and never getting anywhere. Strangely, however, I am super quick at my tables, and, if not pressed for answers, can usually get mental arithmetic problems done correctly, and faster than others who have the benefit of paper and pencil.

Yes it "id" lol. ;)

Wouldn’t there have to be parentheses around the 10 divided by 2? To get 9?

@@bwilderd5082 - No, because of order of operations. Division takes precedence over Subtraction, so you have to solve that part BEFORE you can subtract the answer from 14.

You sum the equation backwards 10÷2=5 then the 4+3×2=14 14-5=9

Yes! Use parentheses.

he wrote it wrong and left out the 2nd set of parentheses

THANK YOU! And to your repliers (so far). This is blatantly obvious. There is no point to these videos, other than to drive comments. (Which I guess makes the author money somehow). There are multiple correct answers, depending on how or when you were taught math, because there are multiple methods for solving this. Only the use of parentheses is undisputed and universal, across all methods ever taught. So presenting problems without the correct use of parentheses only serves the author's quest for income, not teaching anyone anything useful. More shameless use of social media, making us all dumber the more we use it.

@@MarkTubeG How long ago did you learn math? And where?

@@MarkTubeG Parentheses is a bother. They take time to write, and they clutter up the text. Therefore it is advisable to avoid using more parentheses than necessary to convey your meaning. The PEMDAS, BODMAS, etc. mnemonics has been standard (in English-speaking countries), and the Order of Operations we use today has been in existence since the sixteenth century (the 1500's), although there has been discussions as late as the early 1900's about whether multiplication should take priority over division. But addition and subtraction has had lower priority than subtraction and division since before the notation we use today had been formalized. So if you have learned to use +,-,x and /, somebody SHOULD have explained to you that 4+3*2 is 10, not 14. and likewise that 7*2-10/2 is 14-5 is 9, NOT 7*2-10/2 is (14-10)/2 is 2.

By being able to solve these equations indicates to academics and employers that you have an ability to learn to a specific level of education! What your employers saw was that you have attained a standard of Math education which they sought for the position they were hiring!

@@BraddersMusic Okay, I won't attempt to rebut your position. Before I was interviewed for a career position, I took a battery of tests that took a half-day. The interviewing and hiring supervisor told me that I had the highest score they had ever seen! The test had a lot of math and logic questions, but I did not use, or need, the advanced math. I will state that the job was not for a rocket scientist. I started as a management analyst, progressed to a program analyst, and finally became a program manager.

That would have really helped me get through algebra. Math kept me from becoming a medical doctor, because you know how important algebra is to diagnosing and treating patients. Instead I became a lawyer, no algebra there, and I can sue people, including doctors.

In Canada, we were taught the same. BEDMAS lol!!! Brackets, exponents, division, multiplication, addition, subtraction. Would this format still apply?

Wow, that is awesome!

Yes so the answer is 2

I do agree the answer is "2" 4+3:7 x2:14_10:4 /2:2 is that fine or not

No you must do the division after the multiplication I was wrong initially what I said@@danle161

Yes you are correct Why does he and others not just write the equation in the correct form

The abomination that is PEMDAS is only recognized in the USA and France. It is a secret decoder ring that invites error through lack of consistency the world over. Use parentheses or go home.

I'm in UK got taught BODMAS rule at school - Brackets, orders, division, multiplication, addition, subtraction. :)

It like totally is, but it'd called BODMAS. Brackets are called brackets in proper English. OK, the O is "of", but close enough.

I was also taught BODMAS in the UK, way back in the fifties, and it was probably taught long before that.

Using PEMAS would give the right answer. Parentheses, Exponents(none here), multiplication, addition and subtraction.

I agree completely. The world would be a better place if PEMDAS was lost forever, replaced by parentheses.

which is wrong. It would be the case if the 10/2 were in ( ) but since they aren't it goes 14 (the answer to the first part) -10 (or 4)/ 2 which is 2.

PEMDAS should have been laid to rest decades ago. I first heard of it in 7th grade; our teacher acknowledged that it is a sloppy way to write expressions but the book we had at the time used it. FWIW, the science book we had ridiculed the hoax of continental drift, too. Why it is still in use is beyond me.

however the 10/2 isn't in ( ) so you wouldn't do it as 14-5; you'd do it as 14-10 (4) /2 which is 2.

It wasn't confusing the way that it was written.

@@rich7447 One way fits all, or language misunderstanding.

@@consciouspi That's why language, and math, have rules. Order of operations is one of the more basic.

@@rich7447 absolutely. No different rules. ...have to know what you are doing before hand, what you want to know, if some math functions formulas ignore basic rules. Should stick to proper rules. Slang leads us astray.

When we learnt maths , this is how they gave with all the brackets. So it was very easy.

Just explain how you arrive at the answer leave the padding out of the video until the end .

To be technical PEMDAS is part of the common computer languages, but others don't recognize it. Relying on it, instead of using parentheses for clarity, is a mistake. I'm a bit touchy about careless expressions in programs. Short form: I dealt with a loss of traffic on one of our microwave systems. All the channels worked but one. We had recently installed an update on the alarm and control equipment, and that was the problem. The new one had a bug: the second set of alarms were accessible with a command that should be &H10, but when somebody wanted to look at those alarms the new software sent 10 - the command to loop back T1 #10. Sloppiness like PEMDAS makes me lose sleep once in a while.

While parentheses can be added for clarification, they aren't required for this problem to be properly understood. The definitions and meanings of operations, symbols, etc... are written in such a way as to avoid ambiguity. Ambiguity only arises when arithmetic isn't taught properly, remembered correctly, or the test question is poorly written (which isn't the case with this problem).

You are correct in that you work left to right. But you have to do multiplication and division before addition and subtraction. The answer is 9. Its baffling how so many people in all these videos forget basic math.

Head of knuckle...

Exactly. That is why this equation should have been written as (4+3)2 - (10÷2) for the answer to be 9.

Exactly. He’s incorrect. The second set of brackets is missing.

Thank God I’m not the only one that came up with two. I thought maybe I was getting senile in my old age.

Order of operations always comes into play when parathesis are not in place. You have to do 10÷2 before doing any subtraction and addition functions(except what is in parathesis-those always come first).

@@garylewis4938 No, it doesn't. Your order of operations is a convention not a mathematical rule and there is no justification for it. In the absence of parenthesis or brackets you work out the sum from right to left in the same way that you read this sentence. The mathematical rule is that you do the sum in parenthesis or brackets first. Thus you start with (4+3)2 which equals 14, then subtract 10 and divided the result by 2 which equals 2. If the question setter wanted the division to be done first, they would have placed it in parenthesis or brackets to show that was what they wanted. Therefore the correct way is to write the equation so that there is no doubt what the order of operations is by placing the parenthesis or brackets where the question setter wants them to be applied. Thus for the answer to be 9 the equation should be written (4+3)2 - (10 divided by 2) and there would be no discussion on the order of operations. In conclusion, the order of operations convention that you believe should be applied is nothing more than a device to spread unnecessary confusion and unnecessary arguments. Equations should always have parenthesis or brackets to clearly show the order of operation as everyone would then be able to understand that and we would come to the same answer without any disagreement! Permas/BOMAS

2 is the answer.

I am glad you brought this up! I was taught the same way as you were. Again Jackson, Thanks for posting.

It's 4+3=7x2=14, but then you subtract 10/2, or 5, so the answer is 9. Do the multiplication before the subteaction.

Exactly. If the 10 is supposed to be divided by the 2, indicate that with parentheses, not acronyms.

The order of operation is obvious, if you know the rules

Because that would not be confusing

Because this "teacher" teaches acronyms (BODMAS, PEMDAS, BOBS, DMSRS, etc.), not Algebra. It is memorizing acronyms what matters; it is not logic and brains which matter, anyway. And it depends ( "Algebra depends") on the country you happen to be at a certain time (UK, CANADA. USA -and even the State, for example Minnesota, where DMSR is the correct one), to be "trained"). OMG! What a fake teaching.

How about simplifying it to 9 = ?

I'm not sure at all if precedence of operators is a "thing" in Pascal or Ada.

God, you are right! Speed it up.
