What are mathematical formulas?

A formula is a mathematical rule or relationship that uses letters to represent amounts which can be changed – these are called variables. Formulae contain equals signs, as do equations, so it can sometimes be difficult to tell the difference between an equation and a formula.

What is the formula of XY?

The formula is (x-y)³=x³-3x²y+3xy²-y³. You convert it to (x-y)³=x³-3xy(x-y)-y³ for an illustration. You take the drawing of the formula (x+y)³=x³+3x²y+3xy²+y³ from above and replace a by the difference x-y. Then the edges are (x-y)+y with different combinations (on the left).
