The Building Blocks: Numbers, Equations and Functions
You start with the rules that all of algebra rests on -- numbers, exponents, radicals, polynomials and factoring -- and use them to solve equations and inequalities. By the end you meet the idea of a function and can read its graph.
Class 1Real numbers and the basics of algebra
The numbers and rules everything in algebra rests on.
Class 2Exponents and scientific notation
A short way to write repeated multiplication and huge numbers.
Class 3Radicals and roots
Square roots and beyond, and how to handle them.
Class 4Polynomials
Adding, subtracting and multiplying expressions with powers.
Class 5Factoring
Breaking a polynomial back into the pieces multiplied together.
Class 6Rational expressions
Fractions where the top and bottom are polynomials.
Class 7Linear equations
Solving equations where the variable is to the first power.
Class 8Quadratic equations
Solving equations with a squared term.
Class 9More equations and complex numbers
Other kinds of equations, and numbers beyond the real line.
Class 10Inequalities
Solving when one side is bigger, not equal.
Class 11Functions and their graphs
The idea of a function, and seeing it as a picture.
Class 12Semester 1 review: from numbers to functions
Pulling the basics together and solving real problems.
