In this video math lesson we will learn how to classify graphs and equations as linear or nonlinear functions. We will define a linear function as a relationship between two quantities with a constant rate of change. The graph of a...

In this math video we will learn facts about linear functions. We will discuss the characteristics of a linear function in slope-intercept form. We will review that slope-intercept form is y=mx+b. We will discover that m represents the...

This video covers the order of operations; including what the acronyms BODMAS, BIDMAS, BEDMAS and PEMDAS/PEDMAS stand for. We explain in which order to calculate math problems, the importance of the order of operations, and provide...

Are algebraic equations giving you a headache? Fear not! In this comprehensive tutorial, I'll break down the art of solving algebraic equations using opposite operations.

This video explores the intriguing world of equations, showcasing how they can lead to straightforward solutions or unexpected contradictions. Viewers are guided through solving equations with no solution, equations with one solution,...

Do you need a quick refresher on how to solve one-step equations using multiplication and division? Then this video is for you! I will show you the step-by-step process for solving equations by walking you through several examples using...

This video explores a different way to think about and visualise algebra using rods. In this video we use the rods to visually represent unknown values. We explore forming expressions and equations using these rods. There are two...

This video provides a variety of practice questions and answers on the topic of identifying surds.

Sorting Groups of Expressions identifies the differences between equations and expressions by sorting a group of equations and expressions into groups based on the definitions.

Equations: Fractions and Mixed Numbers solves real-world problems involving multiplication of fractions and mixed numbers by using equations.

In this video, we explore the concept of literal equations, which involve equations with multiple variables. By following systematic steps such as isolating the variable of interest using properties of equality, we can solve for specific...
