Practice makes perfect

We are asked to evaluate the given expression using the Distributive Property. To do so, we need to distribute 4 to the terms inside the parentheses.

4(8-7)

a-b = a+(- b)

4[8+(- 7)]

Distribute 4

4(8) + 4(- 7)

a(- b)=- a * b

4(8) + [- 4(7)]

Multiply

32+[- 28]

a+(- b)=a-b

32-28

Subtract term
