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

Nov 18, 2015

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

#### Explanation:

$\left(12 - 9\right) = 3$
This gives us:
$4 + 3 \left(3\right)$

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

Next step is multiplying and dividing.
$4 + 3 \cdot 3 = 4 + 9$

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