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

$\begin{gathered} -8-(-10) \\ -\times-\Rightarrow+ \\ -8+10 \\ 10-8=2 \end{gathered}$

Hence, Taylor is correct and his friend is wrong
