Algebra

Algebra fundamentals, explained step by step

This beginner course rebuilds algebra from its most basic building blocks: the sign of a number, addition and subtraction of real numbers, and what "opposite" actually means. From there it works methodically through multiplication, reciprocals, least common multiples, fractions, and division before introducing variables and algebraic expressions.

Who it's for

Anyone starting algebra with little or no prior experience, whether that's a student catching up, someone returning to math after years away, or a learner who wants the concepts explained in detail rather than assumed.

Key takeaways

• The rules governing signed numbers and basic operations
• How and why parentheses change multiplication
• Working confidently with fractions and reciprocals
• Evaluating algebraic expressions once variables are introduced
• Exponents, greatest common factors, and the properties of real numbers

The video format lets you pause and rework each concept until it clicks before moving on.
