For example, what does an exponent mean? If you know what an exponent means, you'll have no difficulty remembering that x²x³ = x⁵ but (x²)³ = x⁶.For example, know the meanings of "solve for x", "simplify", and "factor". Solving for x is something you do with an equation or inequality: you figure out what numbers could be plugged in for x to make the equation true. Simplifying and factoring are ways of rewriting an expression: simplifying rewrites so everything at the outermost level is added or subtracted, and factoring rewrites so everything at the outermost level is multiplied or divided—without changing the result of the calculation.

For example, what purpose does factoring serve in algebra? Factoring makes multiplication and division easy (at the cost of making addition and subtraction hard). When multiplication and division are easy, you can do things like cancel in fractions and solve for x when x appears in multiple powers in one equation (like both x and x²).
