Are you wondering what will get you the most profit? Do you want to know the likelihood of completing a difficult task? Or are you just curious about what will happen if you stick your tongue in a power socket? Then you’ll probably want to master the art of equations!

Equations are mathematical statements that assert the equality of two expressions. Expressions can pretty much be anything, from numbers to squiggly lines, as long as they have a meaning. They have to follow rules though, much like language. If you said something like: The sheep the in at for my kitty kat, I would slap you across the room for breaking the syntax rule, not to mention for speaking in tongue. So an expression cannot be 14+/²,// because you are using symbols that have a set meaning, and 14 plus divided by squared comma divided by divided by, makes no sense. A proper expression would be something like 14xyz², in which case the letters usually stand for numbers you have to insert.

Now to make an equation you need an expression on either side of the equal sign “=” to denote their equality. If we take a simple equation, like A=lw (where A stands for the surface area of a rectangle, l for length and w for width), we can analyze it to understand the components. Simply put, this says that if you take the length and multiply it with the width, you get the surface area. Let’s insert some numbers and see if it works: take 10 for l and 5 for w, then you get 10 times 5 which equals 50. According to the equation, which says that the left side is equal to the right side, A must be 50 because l times w is 50. To see that this is true, you can take a rectangle with a length of 10 and a width of 5, and you will also see that the surface area is 50.

Obviously I took a very simple example to explain equations. If you do proper maths or physics, you will encounter equations that will look like mumbo-jumbo and make you poke out your eyes with a pen. Most of them will contain a series of symbols (by which I mean anything but numbers) that usually stand for the answer of smaller equations.

The really fun part is that you can make equations of your own and test them. Let’s try it, shall we? You want to calculate your chances of success at trying to woo a suitable mate. So let’s take S (SCORE), h (how’s my hair?), t (did I brush my teeth?), l (am I feeling lucky?), n (how much of a nerd am I?) and finally g (how much does she hate my guts?). In proper form this will be: S=h+t.l-n/g². If the answer is anything above the square root of a dolphin, you’re gonna get lucky tonight!
