In Mathematics, a limit is defined as a value that a function approaches, as the input approaches to some value.Limits are important in calculus and mathematical analysis and used to define integrals, derivatives, and continuity.
And what's neat about it is the property of limits kind of are the things that you would naturally want to do.
And if you graph some of these functions, it actually turns out to be quite intuitive.
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. The limit as x approaches c of f of x minus g of x, is just going to be L minus M.
It's just the limit of f of x as x approaches c, minus the limit of g of x as x approaches c. And we also often call it the difference rule, or the difference property, of limits.
This fact works regardless of number of functions we seperated by “ ” or “-”.

This is often called the sum rule, or the sum property, of limits.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. And we could come up with a very similar one with differences.And finally-- this is sometimes called the quotient property-- finally we'll look at the exponent property.So if I have the limit of-- let me write it this way-- of f of x to some power.
