26.(-8) X(-4) = (-4) X(-8)
Section B

B. Commutative property for
multiplication
C. Commutative property for addition
27.5+[(-3) + (-2)] = [5+(-3)2+(-2)​

Answer 1

Step-by-step explanation:

25. (-7) + (-2) = (-2) + (-7)

- 7 - 2 = - 2 - 7

- 9 = - 9

26. (-8) × (-4) = (-4) × (-8)

32 = 32

27. 5 + [(-3) + (-2)] = 5 + (-3) 2 + (-2)

5 + (- 3 - 2) = 5 + (-6) - 2

5 - 5 = 5 - 6 - 2

0 ≠ - 3
