    oh i know how to do that! but what about stuff like -2-x-x and x+x+x+10

    okay -x-x? that is -2x because when we have -vs- we add. X has conf of one when no value is being denfined 3x+10 because again you are adding 1 which is what the x has a value of.

    unless the -2 has and x like this -2x you can not put together. since our -2-x-x the only thing you can do here is -2 -2x terms don't match.

    in other words when you an X unless there a number in front think one. But not when there X^2 no.

    okay let us do in this in steps. first what can we do with all X terms. Recall x terms are numbers and or x's that can added or subtracted or divided?
