By writing an expression in its simplest form, it makes it as easy as possible to understand it. For example, if you write out
12(x - y)y2x-2x2(x-3y-2x3)/(4)(x-y)
Then you'll have very little luck understanding it. However, if you simplify this expression, you simply get
3
w - 9 is in its simplest form.
simplify it, reduce it
