= 90 - 25 * 3 + (3 + 12) * 3
= 90 - 25 * 3 + (15) * 3 (Do parenthesis first)
= 90 - 75 + 15 * 3 (Then Multiplication left to right)
= 90 - 75 + 45 (Then the second multiplication)
= 15 + 45 (Addition)
= 60
Everyone else who posted a different answer did not do the mathematical operations in order.

90 - 25 x 3 - (3 + 12) / 3 = 60
90 - 25 = 65
65 x 3 = 195
195 - (15) = 180
180 / 3 = 60
