Question

Simple question, just want to know if I did it right. If not, please explain how to do it.
42-81=-41
Is this right?

Answer 1

Hint* If you subtract 42 from both sides of this equation...does it come out true?

Answer 2

Answer 3

There we go...and lets see

\[\large 42 - 81 = -(81 - 42) = -39\]
