A
B
C
The correct answer
The answer is 9
Why is 9 the correct answer?
6÷2(1+2)
= 6÷2(3)
Well, if you remember from your school days, according to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First, take 6 and divide it by 2, and then multiply by 3.
6÷2×3
= 3×3
= 9
The answer is therefore 9.
Did you pick the correct number? Congratulations!
