Question

Preciso resolver essas expressões.

a) 60- ( 14 - 4 +6 ) - 16 - 6 =
b) ( 140 + 20 -10 ) - 63 - ( 18 - 10 - 8 ) =
c) 135 - 35 + ( 13 - 8 + 4 ) - 7 + 20 =
d) 500 + 36 - ( 8 + 12 - 6 ) + 21 - ( 80 + 123 ) =

Answer 1

a)60-(14-4+6)-16-6= 60-16-16-6=60-32-6=60-38=22

b)(140+20-10)-63-(18-10-8)= 150-63-0= 87

c) 135-35+(13-8+4)-7+20= 135-35+9-7+20=122

d) 500+36-(8+12-6)+21-(80+123)= 500+36-14+21-203= 340
