Answer 1

Respuesta:

1•-1 + 2 -3 + 4 - 5 -6 =

15+2+4=

15+6=

=-9

2•- 4+5-6+12+45-67=

-77+5+12+45=

-77+62=

=-15

3•(-45)*2=

-(45x2)=

=-90

4•(-12) ÷ (-4)=

12÷4=

=3

5•5 * (-2) - 3 * (-1) - 5 * 2 + 7 =

5x(-2)-3x(-1)-5x2+7=

-10+3-5x2+5=

-10+3-10+7=

=-10

6•24 ÷ (-2) - 3 * 4 - 6 ÷ 2 - (-3) * (-2) =

-12-3×4-6÷2-(-3)×(-2)=

-12-12-3-(-3)×(-2)=

-12-12-3-6=

=-33

7•3 - (5* 2) + 12 ÷ (-3) - 4 * (6 - 4) =

3-10+12÷(-3)-4×(6-4)=

3-10-4-4×(6-4)=

3-10-4-4×2=

3-10-4-8=

=-19

8•2 -[2 - (-4) -12 ÷ (-3)] - (5 * 3 - 1) =

2-(2+4+4)-(15-1)=

2-10-(15-1)=

2-10-14=

=-22

9•4 -[2 - (3 - 4 * 3)] + [4 - (24 ÷ 4)] -4 =

-(2-(3-4×3))+(4-(24÷4))-4=

-(2-(-3-12))+(4-6)=

-(2-(-9))+(-2)=

-(2+9)+(-2)=

-(2+9)-2=

-11-2=

=-13
