-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
Well, darling, radical 5 plus 2 radical 5 is simply 3 radical 5. It's like adding apples to apples, just with more math and less fruit. So, go ahead and flaunt that math prowess like a boss!

5 + -8 = 3 + 12 -3 is not equal to 15
A Huge ASS
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.

3 plus 5 is equal to 8.
-1
5 + (-3) + (-5) = -3
3root(6)+5root(2) you really answered it yourself!
3 plus 4 is 7, not 5.
5+n+3 = 8+n
