Question

How do you solve `-6- ( 5- - 2) + 2`?

Answer 1

Use the order of operations PEMDAS and the rules of positive and negative numbers.

Explanation:

The first thing to do is the parenthesis `( 5 - - 2) = +7`

a - - = +, so ( 5 + 2) = + 7

Think a negative is bad and to subtract is to take away.
So to take away something bad is good. something good is positive. so - - 2 = +2.

Next working from left to right take

`- 6 - ( +7) = -13`

Think: " negative means to go down "so you go " down six and then go down another 7"

`-6-7 = -13`

Continue working from left to right

`-13 + 2 = -11`

Think negative means to go down and positive means to go up.
so go down 13 but then up 2

One way to remember PEMDAS is to think like this

PE ( Parenthesis and Exponents) physical education
MD ( multiplication and Divisioni) Medical Doctor.
ASap ( addition and subtraction ) As Soon as possible

If you get hurt in PE call a Medical Doctor As Soon as possible.

Do Parenthesis and Exponents first. Then do multiplication and division at the same time working from left to right because a Medical Doctor is only one person.
Then do Addition and Subtraction at the same time working from left to right because As Soon as possible is one time, now.
