Question

What is the answer to 8 - ( - 11 )

Answer 1

In order to solve this exercise, you need to remember the following Sign Rules:

`\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ -\cdot+=- \\ +\cdot-=-_{} \end{gathered}`

Then, given:

`8-(-11)`

You have to multiply the negative signs:

`=8+11`

Finally, since both numbers are positive, you have to add them. The sum (the result of the Addition) will be positive. Therefore, you get:

`=19`

The answer is:

`=19`
