I'm half way through and have no freaking clue why I keep watching if not by mere curiosity and great enthusiastic explanation. The abstraction have always been annoying to me but the mathematical prowess have still always been interesting, to lock things in a logical place of understanding and a mechanical processing that guides me between the unknown real shape of reality and my swimming through with my imagination gap filling 'power'.

Ans should be only 9

But shan't we obey BODMAS rule

Sir your videos are amazing but please work to reduce reverberations in your classroom

The Boss, Mr Hoskin, would not approve. Where are the Australians?

The answer is not 9 because what is we replace ÷ by /

Well, according to the rule there should only be one answer. That is 9. The rule is bodmas. First, you solve what's inside the Brackets, then "off" which is simply multiplication but with different sign. There's no "Off" in it, so next is Divide. Hence, we first do the brackets which equates to 3, then "off" but its absent, so we do division of 6 by 3 which equates to 3, then multiplication which equates to 9, the only answer according to me. Butttt...don't believe me. That guy's a profesional mathematician with far more experiece than me. If he's saying it can be both then it can be both. There must be something wrong with the explanation I gave.

its 7

Since I'm not anything close to being a math guy, the only thing that I understand from this video is that it's a math class! Fantastic!

Obvious answer is mitochondria

9

It's Yes, 1

It's 9

To determine the value of the expression 6÷2(1+2), we need to follow the order of operations, often abbreviated as *PEMDAS/BODMAS:* P/B: Parentheses/Brackets E/O: Exponents/Orders (i.e., powers and square roots, etc.) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right) Let's break down the expression step by step: 1. Parentheses/Brackets: Evaluate inside the parentheses first. 1+2=3 So the expression becomes: 6÷2(3) 2. Multiplication and Division (from left to right): Perform the division and multiplication from left to right. Here we have two operations: division and multiplication. According to the order of operations, we proceed from left to right. 6÷2×3 First, perform the division: 6÷2=3 Then, multiply the result by 3: 3×3=9 Therefore, the expression evaluates to 9. *Explanation:* The confusion often arises because some might interpret the expression differently, grouping 2(3) together before performing the division. However, according to standard mathematical conventions (PEMDAS/BODMAS), multiplication and division are performed from left to right as they appear. Thus, the correct and mathematically logical interpretation of the expression 6÷2(1+2) is: 6÷2×3=3×3=9 *So, the answer is 9.*

This guy is wrong. The division symbol only holds true for the term after it (which is 2 in this case). If you wanted to include the (1+2) within that division process, you would have to write the equation like this : 6÷(2(1+2)). Then the answer would be 1. Another problem people I saw is that people don't know that if there is brackets without any symbol it implies you have to multiply. So 2(1+2) = 2 x (1+2). Follow these rules and you will see the correct answer is 9.

It's 9.

I actually had fun watching this

but how do you go from 0! to -1! with the same logic of from a^0 to a^-1? what do you divide it by?

Why isn't the binomial variance n*p*q?

Wish I saw this before my maths exam 😭

I wish you had a full lesson on binomial theorem

I feel a desperate need to learn English because of your videos because I use the translator and I feel excluded. 🙂😭

Great to see CTHS is working on their assessments lol

Good luck from NYC! ❤ Have a great trip, it would be great to go to your lectures at NY. Wish you a well planned smooth journey in US 🎉

1)6÷2(1+2) 2)6÷2×3 3)3×3=9

9

That was fun :-)

What I personally think the reason for the principal argument to be restricted between -pi and pi is because of the ease of multiplication. When we multiply two or more complex numbers they elongate by the combined (product) modulus and rotate by the combined (sum) argument . The disjoint interval given for the principal argument helps if multiplication was considered as a transformation such that the product measures as 1+ 0i in the transformed coordinate system. When there are multiple complex numbers in the same argand plane this basis transformation could be helpfull. Some problems in physics are solved in such a way. Hope this helps.

Nice video ❤

#dayan kiriwaththuduva a mathematician says 1 divided by zero is postive or negative infinity so please come to an conclusion

the correct answer is 9. multiplication and division are at the same level , so you do them left to right . the problem becomes 3*3=9

Ambiguity is the worst. Use brackets to negate it to the best of your ability, because math isn’t supposed to be about finding different ways to interpret the same thing it’s about problem solving. This is stupid. We shouldn’t force ambiguity like this and should just use better notation. Brackets, use the / instead of divide by symbol, etc.

6÷2(2+1) = 6 ÷ 4 +2 = 3.5 💀💀💀💀 Lol just kidding

I did this with calculator and GOT 9 NOT 1

The answer is 9 obviously In mathematics we dont use ÷ symbol for the same reason The equation is (6/2)(1+2) And not 6/[2(1+2)] Thats why it is 9 And not 1 The (1+2) part is in numerator and not denominator

i thought it was 6

great sirvm i am Ramesh from india, kindly make it with some activity

UGHH, why study in my class not as happy as here

It's 7

9

Why did i came here ? Asn: just for entertainment😂

If you use BEDMAS then its 9

There’s no way this equation could be 1 but 9, is just wrong to multiple 2 times 1+2 since you literally have a division right next the 2. You could either resolve the division first which will get you 3 and then multiply by (1+2) or solve 1+2 times 6/2. I don’t even think mathematically speaking that the answer 1 is correct in terms of order and rules.

2:15 he is a magician as well 😂😂😂

WOW. Respect

awesome!
