Question

All of the following expressions represent the sum of n and itself, except _____.



n + n

2n

n^2

Answer 1

Well if you think about it.
THe sum of n and itself would mean
n + n
Then you can collect like terms because they are both "n" So you would simply add them together. (Imagine n = nectarines) So if you added one nectarine + one nectarine, it would be the same as having two nectarines right?
