But most of these should be fairly intuitive. And they're very helpful for simplifying limit problems in the future. So let's say we know that the limit of some function f of x as x approaches c is equal to capital L. And let's say that we also know that the limit of some other function, let's say g of x as x approaches c, is equal to capital M. Now, given that, what would be the limit of f of x plus g of x as x approaches c? 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.
