Well, and you could look at this visually. If you look at the graphs of two arbitrary functions, you would essentially just add those two functions. It'll be pretty clear that this is going to be equal to, and once again, I'm not doing a rigorous proof. I'm just really giving you the properties here. This is going to be the limit of f of x as x approaches c plus the limit of g of x as x approaches c, which is equal to, well, this right over here is, let me do that in that same color, this right here is just equal to L. It's going to be equal to L plus M. This right over here is equal to M. Not too difficult. This is often called the sum rule or the sum property of limits. And we could come up with a very similar one with differences.
