Question

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

Answer 1

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 `(-6 / 2)`

`-6/2 = -3` A negative divided by a positive is a negative.

Think about this a negative is something bad a positive is adding something. Adding something bad is bad or 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 +( -3 xx 3)" so " ( -3 xx 3) = -9` leaving

`-4 + (-9)`

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 + (-9) =- 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)
