There are many reasons one may want to simplify, rearranging to find specific values - or maybe just making it simpler

Well, let's do some examples:

y(x(3+2)) +2 = -2y +2 < I just made this one up, it looks really complicated right now, none the less it can be simplified easily

y(3x+2x) + 2 = - 2y +2

3xy + 2xy + 2 = -2y +2

5xy + 2 = -2y +2 <-- the +2's dissapear because they cancel out

5xy = -2y

And there we have it, that long expression has been simplified to something really simple.

Another example:

3(4(x+3(2 +z)) - 5)= 3y <- you can start where ever, I like starting in the middle

3 * (4 * (x + 3*(2 + z)) - 5 ) = 3y <- here it is spaced out, we get a much better view

3 * (4 * (x + 6 + 3z) - 5 ) = 3y

3 * (4x + 24 + 12z - 5) = 3y <- divide both sides by 3 ..

4x + 24 + 12z - 5 = y <- much better

Note: Simplify means solving to a degree, but you can't solve it because it has unknowns
