Also known as "High School Algebra"

OK. So what are you going to learn here?







Reading Math





Now we know what a set is, let us look at different sets of numbers that are useful:

pi symbol

square root of minus one


"Equal To" is nice but not always available. Maybe we only know that something is less than, or greater than. So let's learn about inequalities.




We will be using exponents a lot, so let's get to know them well.

8 to the Power 2




polynomial example

expand vs factor

Graphing Polynomials



And, of course, we need to know about equations ... and how to solve them.



Graphs can save us! They are a great way to see what is going on and can help us solve many things. But we need to be careful, as they sometimes don't give the full story.



Linear Equations


Slope-Intercept Form



A function relates an input to an output. But from that simple foundation many useful things can be built.

doman and range


Equations of Second Degree


Quadratic Graph


We already have experience in solving, but now we can learn more!

3d Box


Solving Inequalities



Exponents and Logarithms


Exponent vs Logarithm

Systems of Linear Equations

What happens when we have two or more linear equations that work together? They can often be solved! It isn't very hard but can take a lot of calculations.

A Matrix



Is it likely? You be the judge!

Sequences, Series and Partial Sums

A Sequence is a set of things (usually numbers) that are in order. We can also sum up a series, where Sigma Notation is very useful.

sequence term



These last few subjects use what we have learned above.


And that is all!


But there are many other interesting algebra topics such as:
