# How do you evaluate -4+ ( - 6\div 2) \times 3?

Use the order of operations Parentheses Exponents, Multiply and Divide, Addition and Subtraction.

$- 13$

#### Explanation:

One way of remembering the order of operations is If you get hurt in PE call a Medical Doctor As Soon as possible.

First do Parentheses $\left(- \frac{6}{2}\right)$

$- \frac{6}{2} = - 3$ A negative divided by a positive is a negative.

Next do multiplication and division from left to right. ( Remember a medical doctor is one person not two, so the multiplication and division must be done together.)

$- 4 + \left(- 3 \times 3\right) \text{ so } \left(- 3 \times 3\right) = - 9$ leaving

$- 4 + \left(- 9\right)$

Next do addition and subtraction from left to right (Remember As Soon as possible is one time not two so addition and subtraction must be done together. )

$- 4 + \left(- 9\right) = - 13$

A negative goes down, a second negative goes down further leaving a more negative number. You go down down down and flames get higher and burns burns burns ( that means it is more negative)
