How do you find the factors of a given number? The teacher will show you how to use a table, test out your answers, and then write all your factors in a list. If you know the divisibility rules, that will also help you out.

The teacher illustrates a diagram to help you learn about perimeter. First she adds the sides together to get the perimeter. Then she shows how to use the perimeter formula to make it a bit simpler.

Multiply a number by itself and that is squaring a number. Simple as that, and, if it's an integer you have a perfect square.

The instructor defines a prime polynomial as much the same as a prime number: they only have two factors, 1 and itself. She further demonstrates what a composite polynomial is to give an example of a polynomial that is not prime.

A few examples of numbers, whole, mixed fraction, and decimal, that can be written in fraction form to prove they are rational numbers.

What is the relationship between squaring a number and taking the square root of a number? The instructor in the video explains the relationship of perfect square and its square root integer.
