PRE-ALGEBRA
Build the bridge from arithmetic into algebra: extend the number system, combine operations safely, compare quantities, work with powers, then introduce variables and equations.
Learning Path
Follow the sequence or jump directly to the idea you need.
Integers & Negatives
The number line extends both ways. Adding, subtracting, and multiplying negative numbers.
Order of Operations
PEMDAS, operation precedence, and unraveling complex expressions.
Number Properties
Commutative, associative, identity, and distributive properties.
Ratios & Proportions
Scaling, percentages, rates, proportions, and unit price.
Advanced Fractions
Multiplying, dividing, and finding common denominators across complex fractions.
Exponents
Powers, square roots, and scientific notation.
Expressions
Variables and translating verbal relationships into mathematical expressions.
Solving for X
Inverse operations and solving one- and two-step equations.
Reference & Check
Review key vocabulary, then check the ideas that connect the unit.
