If I have something like x + x, (x plus x), I think it would simplify to 2x, but if I have something like x*x, (x times x) it would simplify as x^2, or x squared. Is this correct? Adding like terms creates multiplication while multiplying like terms creates an exponent? If this is the case, would it also work for a larger number of terms? Such as x+x+x equaling 3x and x*x*x equaling x^3 (x cubed). Also, is there anything else to watch out for with these situations? Thanks sent in advance!
