Question

Find the product of (-4) ×(-5)×(-8)×(-10)

Answer 1

The answer is:

1,600

Work/explanation:

A negative times a negative gives a positive:

`\bullet\phantom{333}\bf{(-4)*(-5)=20}`

`\bullet\phantom{333}\bf{(-8)*(-10)=80}`

`\bullet\phantom{333}\bf{20*80}`

`\bullet\phantom{333}\bf{1,600}`

Therefore, the answer is 1,600.
