Answer 1

Respuesta:

1. (-50)(+25)= -25

2. (-20)(-20)(-20) (-20) (-20)= -100

3. (-3)(-2)(-3)(-2)(-3)(-2)(-3)= -18

4. (-23)(2)= -21

5. (-3) + (5)(-2)= (-3)(-2)= (-5)+(5)= 0

6. (-4) (-2) + (-3)(5)= (-4)+(-2)+(-3)= (-9)+(5)= -4

7. (-2)(-5)(3) + (-2)(5)= (-2)+(-5)+(-2)= -9 y (3)+(5)= 8

R: (-9)-(8)= -1

8. (-2)(4) + (-8) - (4)= (-2)+(-8)= -10 y (4)+(4)= 8

R: -2

9. (5)-(-5)-(-2)(-4)= (-5)-(-2)-(-4)= (-11)-(5)= -6

10. (8)(-6) 20= (8)(20)= (28)(-6)= (22)
