Question

How do you use the property’s of multiplication to find the product of -2*(-4)*9??

Answer 1

First, remember that if an expression involves only multiplications, the order in which the multiplications are performed does not affect the final result.

On the other hand, remember that when two negative numbers are multiplied, the result is a positive number.

Starting with the expression:

`-2\cdot(-4)\cdot9`

Multiply -2 times -4:

`-2\cdot(-4)\cdot9=8\cdot9`

Then, multiply 8 times 9:

`8\cdot9=72`

Thefore:

`-2\cdot(-4)\cdot9=72`
