Answer 2

1. -15

2. 16

3. 48

4. 219

5. 65

Explanation:

Remember to do PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

1. 7 - 2(2 + 5) - 8 = 7 - 2(7) - 8 = 7 - 14 - 8 = -7 - 8 = -15

2. 15 + 3 - 2(2 - 1) = 15 + 3 - 2(1) = 15 + 3 - 2 = 18 - 2 = 16

3. 3[9 - (2 + 3)]^2 = 3[9 - 5]^2 = 3[4]^2 = 3(16) = 48

4. 225 + (7 - 4)^2 - 15 = 225 + 3^2 - 15 = 225 + 9 - 15 = 234 - 15 = 219

5. 200 - 5(4 - 1)^3 = 200 - 5(3)^3 = 200 - 5(27) = 200 - 135 = 65
