This would make the problem easier: (10 - 2^2) + 6 is 6 + (10 - 2^2) = 12

This is an addition problem.
Teaching students what kind of problem it is before solving it with PEMDAS would be better.
There aren't parenthesis, you gotta put them in the right place to make the problem an addition problem.
Choose addition first.

This is a subtraction problem:
(10 - 2^2) - 6 = (10 - 4) - 6 = 6 - 6 = 0

6 - (10 - 2^2) = 6 - (10 - 4) = 6 - 6 = 0

I always combine like terms not in parentheses or exponents.

Everyone in the comments is answering 12 :dahell:




The answer is definitely 12, breh.

Addition/subtraction are effectively considered the same operation (subtraction is just the addition of a negative number), as are multiplication and division (division is multiplication by the reciprocal). For order of operations, you don't prioritize one over the other.

So the best way to understand it is:

1. Parentheses
2. Exponents
3. Multiplication and division, in the order of whichever comes first starting from the left
4. Addition and subtraction, in the order of whichever comes first starting from the left
