Question

Find the following products:(–18) × (–5) × (– 4)

Answer 1

We have to find the product of :

→ (-18)× (–5) × (– 4)

As all the three number written are negative integer.

So, Product of odd number of negative integer gives negative sign before the result.

→ (–18) × (–5) × (– 4)

Using Associative property

→ [(-18) × (-5)] × (-4)

= (90) × (-4)   →[ Product of two negative integer is positive integer]

= - 360 →[ Product of positive and negative integer is negative integer.]

The Result of the product  is , (–18) × (–5) × (– 4) = - 360
