Order of Operations

When solving an algebraic problem there are certain steps that must be followed. These steps are known as the order of operations. They create the acronym PEMDAS, which stands for Parenthesis Exponents Multiply/Divide Add/Subtract. They must be solved in this order to get the correct answer

Factoring Quadratic Equations

Factoring quadractic equations is an essential skill in Algebra 2. This skill may seem difficult at first but it’s actually pretty simple once you understand the steps.

Where did we get the Quadratic Formula?

This tutorial derives the Quadratic Formula to show students where it came from.

Function Composition

Function composition is a neat little operation because it allows you to put one entire function in for another function.

Pythagorean Theorem

In this problem, the student will be give two distances as two sides of a triangle, and will need to use the Pythagorean Theorem to calculate how far a woman lives from her workplace. The Pythagorean Theorem is a formula used to determine the length of one side of a triangle if two of the…

Multiple Linear Equations

This particular tutorial will demonstrate how one can find multiple linear equations. If you believe you need a better understanding of single linear equations, please view my 3 part tutorial (Graph proportional relationship). We will first use an example before graphing. You will be given 2 equations: 1) x+2y=1 2) 2x+4y=2 Before we begin, I…
