Core Algebra 2 skills, one at a time.

From Algebra 1: simplify square roots and use the exponent rules, the base Algebra 2 builds on.

Square roots, negative square roots and simplifying roots, all the way to the question only i can answer: what squares to −1?

Meet i, the square root of −1, and do arithmetic with numbers that have a real and an imaginary part.

Read a polynomial's degree and end behavior, divide polynomials, and use the remainder and factor theorems.

Vertex form, the discriminant, and systems that mix a line with a parabola.

Simplify, multiply and divide fractions with variables, and solve equations that have them.

Cube roots and beyond, exponents that are fractions, and equations with a root in them.

Logarithms undo exponents: evaluate them, use their properties, and solve exponential equations.

Add up arithmetic and geometric sequences, and read sigma notation.

Radians, the unit circle, and reference angles.
