Question

Simplify the expression
9− 3(2)2

Answer 1

- 3

Explanation:

These are the steps that I used are:

First, use PEMDAS.

Multiply and divide left to right.

`3\left(2\right)\cdot \:2`

`3\left(2\right)=6`

`=6\cdot \:2` = 12.

`= 9-12`

Second, add and subtract, (left to right).

`9-12=-3`

= - 3.

So, 9 - 3(2)2 = -3.

Answer 2
