# Thread: Which one is correct?

1. ## Which one is correct?

Two Casio calculators; both with a different answer, which one is correct?

Believe it or not, this has become a big debate at work

2. 9 is correct. You work from right to left when the parts have the same priority, supposedly.

3. People are arguing PEMDAS; but they are saying the 2 (3) is multiplied first, because the 3 still has parenthesis. I agree with 9.

__6__
2(1+2)

4. Well you do the parenthesis first.
Then you do the multiplication/division, but you go from left to right.
So you would divide the 6 by 2, then multiply that by 3 to get an answer of 9.

5. Right because there's not actually an equation in the parenthesis after you do 1+2 and number(number) is multiplication, so then you'd do the division and then the multiplication.

Calculators can be wrong! Who knew?

6. 9 is correct! ;3

7. I would not have been able to figure that out LOL I haven't been in school for 5 years + smoked weed/did ecstasy and coke for most of my high school days. *bad brain*

8. 9!!!! , maths was my worst subject lol. But I'll never forget BEDMAS

9. if you are arguing pemdas, than the answer is 1.

10. PEMDAS says 1 but PEMDAS is just a simple mnemonic.

Parentheses first - 2(1+2) = 2(3)
No exponents.
Multiplication and Division are both done in the same step prioritizing the leftmost operations... PEMDAS is a mnemonic, not a mathematical law.

So it would be:
