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.

Fractions, Percentage, Ratios and Proportion
Emphasis here is placed on understanding fractions, percent, and using ratios to compare quantities and set up proportions to solve problems.

Introduction to Algebra

Factoring

Solving Equations

Functions and Graphs

Geometry
This unit focuses on analyzing and understand the characteristics of various shapes, both 2D and 3D.
 Identify, measure, and calculate different types of straight lines and angles
 Calculate the interior angles of polygons
 Solve problems involving a variety of different types of triangles
 Calculate the area of a variety of different types of quadrilaterals
 Solve problems involving circles
 Calculate the areas and volumes of different solids
Scientific Notation
If you’ve ever tried multiplying numbers in the millions and billions on your calculator, you’ve either gotten an error or some number that looks like this:
Notice how this calculator condenses the large output with E17. The E17 is the calculators way of writing:
$\times {10}^{17}\mathbf{or}\times 100000000000000000\phantom{\rule{0ex}{0ex}}$On paper, we can also condense very large or tiny outputs using scientific notation. Examples of numbers written in scientific notation look like the following:
Notice how all of them have the same pattern: a number followed by a decimal and more numbers times 10 to the power of a positive or negative integer. The steps to converting any ordinary number to this notation is outlined below:
To convert a decimal number to scientific notation:
 Rewrite the given number with a single digit to the left of the decimal point, discarding any nonsignificant zeros.
273 → 2.73
2. Then multiply this number by the power of 10 that will make it equal to the original number.
2.73 × 100 → 2.73 × 10²
 Notice how the power of 2 corresponds to the number zeros in 100.
The first video provides a quick tutorial of what’s stated above, including some examples where the number is negative, between 1 and 1, and numbers greater than 1.
 If you’d like more examples, watch part 2 here.
There will also be times when you’ll be expected to go from scientific notation to standard, decimal notation. Let’s make sure we know how that’s done too. Here are few examples to follow along to:
