Introduction to Magnitude
Description
A detailed tutorial of how to solve for magnitude. Step by step tutorial including several examples of how to solve for magnitude for reference.
Overview
The magnitude refers to size – in mathematical concepts, what is larger? What has a greater value or quantity? This is what you look for when arranging things in order of magnitude. Several different measurements are considered to be types of magnitude – examples are volume, area, and length. Things that can be ordered by magnitude are fractions, line segments, planes, solids, and angles. Magnitude is considered to be measured only in positive, not in negative – not to say that the absolute value is taken, just that negative numbers are not included.

Four-Color Theorem Explained
Description
A detailed tutorial on the four-color theorem. Step by step tutorial including several examples of the four-color theorem for reference.
Overview
The four-color theorem is a concept in math that states that given any seperation of a plane into seperate regions, the regions can be colored in using at the most four colors so that no two adjacent regions have the same color. These planes are called maps, and in fact a real map is an example of one. In order for two regions to be adjacent, they must share a side. If they share a point they are not considered adjacent.
