Synthetic division can make life easier when you are dividing polynomials. However, it is only useful in certain specific situations, such as when dividing by a linear monic polynomial. So, can...

Prime numbers are the building blocks of integers, and they are important in number theory and cryptography.  There are lots of prime numbers that we know of, but this still leaves the question...

You will often see both linear and exponential growth functions in science and math courses.  However, it is helpful to see the differences between them compared side-by-side. So, what is the...

We know that functions are useful in algebra and calculus, but there are many different distinctions we can make.  One of these is the idea of an onto function (also called a surjection). So,...

Knowing the concavity of a function helps us to get an idea of its shape and behavior.  We can tell concavity by looking at the graph of a function or by looking at the sign of its second...

When dealing with polygons in geometry, it sometimes helps to know the total measure of all interior angles.  We can also find the exact measure of each angle in a regular polygon. So, how...
