Answer 1

Explicație pas cu pas:

A 3+3:(-3)=3+(-1)=2

B 11+6×(-1)=11+(-6)=5

C -1-2:(-2)= -1-1=-2

D +9+7×(-2)=9+(-14)= -5

E -11-5×(-2)= -11-10= -1

F 0-9:3=0-3= -3

G 0+9:(-3)=0+(-3)= -3

H 2×(-5)+5×(-2)= -10+(-10)= -20

I 12:(-6)-4:2= -2-2= -4

J 2009×0-2009=0-2009= -2009

K 2+(-2) la puterea 2=2+4=6

L 5+(-1) la puterea 5 +(-5) la puterea 0=5+(-1)+1=4+1=5

M 45:(-9)+45 la puterea 1= -5+45=40
