Answer 1

18

Step-by-step explanation:

The order of operations for mathematical expression is the following.

0. Parenthesis

,

1. Exponents

,

2. Multiplication & Division

,

3. Addition & subtraction

Therefore, in our case, we first evaluate the parenthesis in our expression.

Since, 4x3 = 12 and 9 ÷ 3 = 3, our expression becomes

`12*3-6*3`

Next, we carry out the multiplication ( since there are no exponents in our expression). Since 12 x 3 = 36 and 6x 3 = 18, the above becomes

`36-18`

which we evaluate to get:

`36-18=\boxed{18.\text{ }}`

Hence, we conclude that

`\boxed{(4*3)*3-6*(9/3)=18.}`
