Everything you need before calculus.
From place value to the unit circle: a complete, connected path through arithmetic, algebra, functions, geometry and trigonometry. Every lesson links to the ideas it builds on.
Place value, the four operations, order of operations and the building blocks of whole numbers.
Numbers below zero, how to combine them, and distance from zero.
Parts of a whole: equivalence, comparison and all four operations.
Base-ten fractions, converting between forms, and percentages in the real world.
Comparing quantities, rates, and solving proportions.
Powers, the exponent laws, roots, radicals and scientific notation.
Variables, expressions, and solving equations and inequalities.
The coordinate plane, slope, equations of lines and systems.
Inputs and outputs, notation, domain, composition, inverses and transformations.
Expanding, factoring, and every method for solving quadratic equations.
Growth and decay, logarithms as inverse exponents, and solving exponential equations.
Angles, triangles, Pythagoras, area, circles, volume and coordinate geometry.
Right-triangle ratios, radians, the unit circle, trig graphs and identities.
Patterns, arithmetic and geometric sequences, and summation — the doorway to limits.
