The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.

For the first one you get:
\(72 - (63-8)\)
\(72 - 55\)
\(17\)

For the second one you get:
\((72-63)-8\)
\(9-8\)
\(1\)

Which mean that The 2 equations are not equal, because \(17 \ \textgreater \ 1\)
Hope this Helps! :D

They are not equal because for each you get different answer.

\(72-(63-8) \\ 72-55 \\ 17\)

\((72-63)-8 \\ 9-8 \\ 1\)

17 and 1 are not equal.

Therefore, the two expressions  72-(63-8) and (72-63)-8 are not equal .
