Question

If a = 2, b = 3, c = 4, and d = 12, evaluate

15 - ab

Answer 1

9

Explanation:

So, if

a=2, and b=3, then all of that other information doesn't really apply to this problem.

So, let's start by substituting:

15 - (2 x 3)

Solve parenthesis, they always come first:

15 - 6, which equals:

9.

Hope this helps.

Answer 2

Answer: 10

Explanation:

because if you do 15-ab it would be 10 because you do 2+3=5-15=0
