When working with fractions, we often want to simplify as much as possible to make our work easier.  Denominators are important when adding or subtracting fractions – especially when square...

When solving an equation, we might find that there is no solution, one solution, multiple solutions, or infinite solutions (we can also say “infinitely many solutions”).   It helps to...

When working with triangles, we often want to calculate and compare side lengths (in addition to angles).  The triangle inequality is one tool that we can use to help us. So, what is the...

Exponential functions are widely used in science, math, economics, and other disciplines.  An exponential function has certain traits that distinguish it from others (such as linear or quadratic...

In math, definitions are the first thing we learn to build our knowledge.  The concepts of equations and expressions are important, but how are they connected? So, what is the difference...

Domain and range are two important concepts when we talk about functions.  Depending on domain restrictions, the graph of a function will look different (and may even have an inverse). So,...
