A) 31+(-40):(+2)

B) -10-20:(+4)

C) (+30):(-6)+(-18):(+3)

D) 7:(-7)+2.(-6)+11

E) (-36):(-4)+3.(-3)

F) 35-6.(+6)+(+54):(-6)

G) 2+(-75):(-5)-4.(-1)

Answer 1

A)
= 31+(-40):(+2)
= 31 + (-20)
= 31 - 20
= 11

B)
= - 10 - 20:(+4)
= - 10 - 5
= - 15

C)
= (+30):(-6)+(-18):(+3)
= - 5 +(-6)
= - 5 - 6
= - 11

D)
= 7:(-7) + 2.(-6) + 11
= - 1 - 12 + 11
= - 13 + 11
= - 2

E)
= (-36):(-4)+3.(-3)
= 9 - 9
= 0

F)
= 35 - 6.(+6)+(+54):(-6)
= 35 - 36 + (-9)
= - 1 - 9
= - 10

G)
= 2+(-75):(-5)-4.(-1)
= 2 + 15+4
= 2 + 19
= 21
