Simplify in Math, like in English, means to make as simple as possible - as "down to the roots as possible".
In the example = 36 + 10 . To simplify fully would be = 46 since that is as simple as it gets.
In algebra, to simplify fully might involve 14 = 2x, where to simplify fully would be to find x (x = 7)
