**simple but vexing, evaluating algebraic expressions: a = 4 b = -3 a – b^2**

Scratching my head on this one.

a = 4 b = -3

a – b

^{2 }

I maintain that the way to solve this is

(4) – (-3)

^{2}

4 – (9)

-5

My colleague says the following is correct

(4) – (-3)

^{2}

4 + 3

^{2}

13

Please let me know what is the right answer, my way or my colleague's way.

Thank you!
