Question

Someone help me Taylor is trying to explain to a friend how -8 - -10 is 2. The friend thinks that -8 - -10 is 18.Who is correct, the friend, or Taylor?

Answer 1

Taylor's claim

`-8-(-10)=2`

Taylor's friend claim

`-8-(-10)=18`

The right solution

`\begin{gathered} -8-(-10) \\ -*-\Rightarrow+ \\ -8+10 \\ 10-8=2 \end{gathered}`

Hence, Taylor is correct and his friend is wrong
