Evaluate the expression using the given values of the variables. Do not skip spaces or type anything except the value of your answer. For the values n = -16 and p = 4, find -n+7p.
-n + 7p now put in the values. -(-16) + 7(4) a negative with a negative turns into a positive. 16 + 7(4) I'm sure you can do the rest :P @phi
any time :)
