Answer 1

Do order of operation. So we must do the "(,)" because it's inside the bracket.
\[\large \large (71-13) * [(10+8/2) - (3*3-2*2)]\]
So let's do (10+8/2) To simplify this parenthesis, we must do order of operation. 8/2 = 4. 10 + 4 = 14.
= (71-13) * [(14) - (3*3-2*2)]
Do the other parenthesis.
(3*3-2*2)
3*3= 9
(9-2*2)
2 * 2 = 4
(9-4) = (5)
= (71-13) * [(14) - (5)]
Do the bracket.
14-5= 9.
= (71-13) * [9]
Do the other parenthesis.
71-13= 58
= 58 * 9 = 522

Answer is 522.
