Question

How do write in simplest form given `42.3+(-27.9)`?

Answer 1

Adding a negative number to a positive number is the same as subtracting the value. Therefore, the answer should be 14.4

Explanation:

`42.3+(-27.9)` is our starting equation. Since all of the terms inside the parenthesis are negative:

`+(-27.9)` is the same thing as saying `-27.9`

Then we can re-form the equation as:

`42.3-27.9 = 14.4`
