Answer:
96
Step-by-step explanation:
64 -[16 x (-3) – 2 x{17 – 25 }] I'm going to take a couple of steps that are very small and they can be combines along with other steps. Combine 16*-3
64 - [-48 - 2*(17 - 25)] Combine what is inside (17 - 25)
64 - [-48 - 2*(-8)] Combine -2*-8
64 - [-48 + 16] Combine what is in the brackets.
64 - [-32] Remove the brackets
64 + 32 Combine
96
