OKAY! Let's start here...

So you're asking, what is MATH? Well... Here's our best definition. Mathematics is the study of quantity, structure, and change. Do you think that's a bit general? It was meant to be. Math is a part of everything in the universe.

You might be a farmer that needs to measure your land or count your crops. You might be a cook who needs to know how much food to buy. You might be a nuclear physicist that is studying the movements and activity of atoms. All of those jobs use math at one point or another. Math is just as important when you go to buy a burger, as it is to help plot the movement of planets.

Ideas and concepts in math are also universal because they are based in logic and deductive reasoning. Proofs, definitions, and theorems rule the actions of math whether you are from China, Great Britain, or another planet. The concept of "one" will always be "one" no matter what language you speak. Even computers speak math. They speak with a binary language (ones and zeroes). If this is all new to you, start with numbers and counting. You have to start somewhere.
