Question

Simplify m - {n + [p - (m + n - p)]}.


-2m + 2p

2m - 2p

-2m - 2p

Answer 1

\[m -\{{n + [p - (m+n-p)]}\}\]
Work from the inside out:
\[m -\{{n + [p - (m+n-p)]}\} = m - \{n + [p - m-n+p]\}\]
continue from there

Answer 2

Remember that when you have a - in front of ( ), you need to change the sign of each term inside the ( ) when you take them out. That's why the \(+n-p\) became \(-n+p\)

Answer 3

\[m-(n+(p-(m+n-p)))\]\[m-(n+(p-m-n+p)))\]\[(m-(n+(2p-m-n)))\]\[m-(2p-m)\]
\[2m-2p\]
