9. »> 6:2*3=3*3=9. First we calculate the numbers in the parentheses and then we perform all the multiplications and divisions from left to right. Finally, we calculate the additions and subtractions.
9. Add first because it’s in parentheses, 6/2*3. Multiplication and division are on the same order of operation, so going left to right, 9. PEMDAS is incorrect; MD are the same, AS are the same.
If the brackets are done first, which they should, then the answer is 1. If this rule is ignored, then the division is done first and the answer is 9. The only debate here is about whether the rule should apply. It always applies, the answer is 1.
