Theorems in daily life are used more commonly than you think. In fact you use at least one every day. Theorems are like temporary solutions to problems. Until something better comes up, that's how you should go about your observation or situaton.
Math is the basis most -if not all- sciences! I wish I could explain but I'll let physics and chemstry do that...
This website actually has one though it is not the best, it can be useful for sketch graohs and finding limits, etc. On the bottom of the calculator there will be a button that says "Make a graph." Just input your equation where it says f(x)=... or g(x)=... there's no difference between them.
2+2^2=6
Ratios are another way of saying a fraction. If you are given a ratio of 4:5 then that equates to 4/5.
