Question

How do you simplify `4+3(12-9)` using order of operations?

Answer 1

Use PEMDAS (parentheses, exponents, multiplying & dividing, adding & subtracting)

Explanation:

Let's start with the parentheses.
`(12-9) = 3`
This gives us:
`4 + 3(3)`

We dont have any exponents, so we skip this fase.

Next step is multiplying and dividing.
`4 + 3 * 3 = 4 + 9`

Then, add and subtract from left to right.
`4 + 9 = 13`

So the answer is 13.
