my daughter has this problem and asks if she did it correct.

a - b + c2 (squared) a = 15, b = 12, c = 4

so is the answer 19 or 13?

15-12=3+16=19

or

16+12=28-15=13

i say 19?

[Empty Hand]

It's 19. Is that how it's written or is it like this?
(a-+c^2.

15-12+4(squared)

15-12+16=19

[Frash Brastard]

first turn the 4 squared into a 16, then solve the problem from left to right.

the second one looks like you went backwards, which would be incorrect.

the first one is correct.

Please excuse my dear Aunt Sally!

(keeping in mind that addition/subtraction are give equal weight so you should work the problem left to right once you've taken care of the exponent)
