Numerical Computation
Here you'll be introduced to the bare basics of mathematics. Topics include commonly used words and phrases, symbols, and how to follow the order of operations.

Measurements
An introduction to numerical computation. Emphasis is placed on scientific and engineering notation, the rule of significant figures, and converting between SI and Imperial units.

Trigonometry with Right Triangles
Here we focus on right angle triangles within quadrant I of an xy plane. None of the angles we evaluate here are greater than 90°. A unit on trigonometry with oblique triangles is covered later.

Trigonometry with Oblique Triangles
This unit is a continuation of trigonometry with right triangles except we'll extend our understanding to deal with angles *greater* than 90°. Resolving and combining vectors will be covered at the end of this unit.

Introduction to Statistics
Calculate the interior angles of polygons
A polygon is a plane figure formed by three or more line segments. The points where the sides meet are called vertices, and sum of the lengths of a polygon’s sides is its perimeter. If all of the sides and angles of a polygon are equal, it is called a regular polygon. In the diagram below, both shapes are hexagons, but the one on your left is a regular, while the one on the right is irregular. Equal sides or angles are illustrated with daggers .
The simplest of all polygons is a triangle. It has three sides and the total sum of its interior angles is 180°. In this section, you’ll learn how to calculate the sum of the interior angles of any polygon. The formula that’s used to calculated the total sum is:
Sum of Angles
$S=180\xb0\left(n\u20132\right)\phantom{\rule{0ex}{0ex}}$Where S represents the total sum and n represents the number of sides. Let’s take a look at four different examples in increasing difficulty.
