Pre-Algebra help
Free Pre-Algebra help with integers, fractions, percents, expressions, and equations. Follow the lessons in order or review the skill you need today.
Where to start
If fractions or negative numbers slow you down, begin with those lessons before working with variables. Then move through expressions and one-step equations: the same arithmetic rules still apply when a number is represented by a letter.
Work through an example with the explanation covered, then try the practice question. If the mistake is arithmetic, return to that number skill before moving to a harder equation.
