Question

A) -17 + (-5) – (-7) + (-3)
B) 1 -81 . 4 – 100 : (-25)
C) 19 – (5 – 6 . 4 +2) . (-9)
D) 60 – 51 + [ - (-70 + 8) – 123] + 74
E) -3 . 4 + [(-30) : (-6) – (-10) : (+5)]
F) -74 – {[+131 – 5 . (-6)] : (-1)} ​

Answer 1

a) -17-5+7-3= -(17+5+3-7)= -18

b) 1-324+4= -(324-4-1)= -319

c) 19-(5-24+2).(-9)= 19-(-17).(-9)=19-153= -(153-19)= -134

d) 60+74-51+[-(-62)-123]= 83+(62-123)= 83-61= 22

e) -12+[5-(-2)]= -12+7= -5

f) -74-{[131+30]:-1}= -74-{-161}= -74+161= 87
