7n^2 + 2n + 6 - 3 doesn't have any like terms

Wouldn't combining "like terms" be similar to?
2y + 5y = 7y
or 8 - 5 = 3
or x^2 * x^3 = x^5
2y + 5y = 7y
or 8 - 5 = 3
or x^2 * x^3 = x^5
I might call the last combining like factors rather than combining like terms, but yes.

thanks!
ozo,
I agree with your terminology, which is why I put "like terms" in quotes just to match the way the question was worded.
naseeam,
So what was your final answer?
