# Pre-Algebra

The fundamentals you learn in my pre-algebra lessons will help you succeed in every other math course you take. In my free tutorial videos, you’ll start with the basics of number classification before learning how to add, subtract, multiply, and divide everything from simple integers to decimals and fractions. From there, you’ll move on to more advanced topics like scientific notation and prime factorization.
