How to Identify a Perfect Square
Description
A detailed tutorial on how to identify a perfect square. Step by step tutorial including several examples of how to identify perfect squares for reference.
Overview
A perfect square is a number that is the square of a non-negative integer – in other words, a positive whole number. The way you can identify a perfect square is that when you take the square root, you should not end up with a fraction or decimal – you should get the non-negative integer. There are many perfect squares, but most of them are large numbers, so many people do not know more than the squares of the numbers one through twelve.

How to Identify Perfect Numbers
Description
A detailed tutorial on how to identify perfect numbers. Step by step tutorial including several examples of perfect numbers for reference.
Overview
A perfect number is a number that is the sum of all it’s divisors (excluding the number itself, which is also a proper divisor). The way that you identify a perfect number is to find all of its divisors. Once you have them all, add them together. If they equal the number, then it is a perfect number. If they don’t, then it is not a perfect number.

How to Use Parametrization
Description
A detailed tutorial on how to use parametrization. Step by step tutorial including several examples of how to use parametrization for reference.
Overview
Parametrization can be used in many different branches of math, including algebra and calculus. Parametrization involves setting up parameters necessary for the complete or relevent specification of a geometric object. This means it is only used when calculating a shape or part of a shape, because that is what a geometric object is. Sometimes, this is nothing more than identifying the parameters. Other times it becomes an involved mathematical process that is used to find out what the parameters are.
