Question

Simplify:
12(5 + 5)2 - 17 +3

Answer 1

My first answer: 5 + 5 = 10 x 12 = 120 x 2 = 240 - 17 = 223 + 3 = 226

If not then,

12 x 5 + 12 x 5 = 120 x 2 = 240, 17 + 3 = 20, 240 - 20 = 220

Explanation:

Numbers in parenthesis are evaluated first.

Answer 2

1186 --- Sorry if I'm wrong -_-

Explanation:

Add: 5 + 5 = 10

Exponentiation: the result of step No. 1 ^ 2 = 10 ^ 2 = 100

Multiple: 12 * the result of step No. 2 = 12 * 100 = 1200

Subtract: the result of step No. 3 - 17 = 1200 - 17 = 1183

Add: the result of step No. 4 + 3 = 1183 + 3 = 1186
