Exercise 22 Page 25

Let's substitute a=4, b=- 3, and c=10 in the expression and then simplify. Remember to carefully follow the order of operations. In this case, before we can evaluate the absolute value, we should simplify the exponent and the subtraction.

| a-b-c^2 |

SubstituteIII

Substitute a= 4, b= - 3, and c= 10

| 4-( - 3)- 10^2 |
