Question

How do you find the difference `-6-(-4)`?

Answer 1

`-6-(-4)= color(green)(""(-2))`

Explanation:

The difference `A - B` is the distance from `B` to `A`.

For the given values, this distance can be demonstrated with the use of a number line:

giving a result of `color(red)(-2)` units.

Typically the rule is that subtracting a negative number is the same as adding the positive version of that number.
So
`color(white)("XXX")color(magenta)(-6)color(green)-color(blue)(""(-4))=color(magenta)(-6)color(orange)(+4)=color(red)(-2)`

Answer 2

-2

Explanation:

`- xx - = +`

`-6-(-4)`

`=-6+4`

`=-2`
