Algebra is one branch of mathematics that studies simplification and problem solving using symbols that are substitutes for constants or variables.

**Algebraic Elements**

Variables / variables are symbols of a number whose value is not yet clearly known, usually represented by lowercase letters a, b, c, …, z.

Constants are the terms of an algebraic form and are numbers and do not contain variables.

If there is a number and can be changed to a = p.q where a, p, and q are integers, p and q are called factors of a.
