# How do you simplify (-3 - 10) using order of operations?

Mar 19, 2018

$- 13$

#### Explanation:

The parentheses around this expression are unnecessary, thus we have

$- 3 - 10$

Since the only operation in the expression is subtraction, there really isn't any need for order of operations. We can just subtract these, or if the negatives seem daunting, factor out a $- 1$ to get

$- 1 \left(3 + 10\right)$

Which is equal to $- 1 \cdot 13$, which is of course $- 13$
