It means to use letters in place of numbers. For example, one algebra property is the commutative property of addition which says that if you add two numbers it doesn't matter which order you add them in. So you would write
a + b = b + a

Remember that the letters, or variables, are just representing an unknown number. Think of all the properties you know of that use numbers, then replace those numbers with variables. I hope that made sense, I'm not very good at explaining things.

Unknowns are usually signified with x, sometimes y, and z. Constants are often signified with Greek letters.
