# How do you simplify 3 - (2^3 div 1) + 5 using order of operations?

Apr 27, 2018

The answer is $0$.

#### Explanation:

$3 - \left({2}^{3} \div 1\right) + 5$

The operations are shown by PEMDAS:

First thing we have to do is take care of the expression inside the parenthesis , $\left({2}^{3} \div 1\right)$

First, ${2}^{3}$ is the same thing as $\left(2\right) \left(2\right) \left(2\right)$, or $8$.

and $\left(8 \div 1\right) = 8$

So now the expression becomes:
$3 - 8 + 5$

Addition and subtraction goes by whatever is most on the left, so it simplifies to:
$- 5 + 5$

So the answer is $0$.

Hope this helps!
