Question

2 + 2[20 − 4(4 + 2)]

Answer 1

2 + 2[20 - 4(4 + 2)]
2 + 2[20 - 4(6)] # simplify inside the parentheses
2 + 2[20 - 24] # multiply -4 and 6 inside the parentheses
2 + 2[-4] # simplify inside the brackets
2 - 8 # multiply 2 and -4
-6 # subtract 8 from 2
Therefore, 2 + 2[20 − 4(4 + 2)] = -6.
