In this post, we’ll be going over the next step, multiplying and dividing rational numbers. Don’t worry, it’s easier than adding and subtracting fractions! Multiplying/Dividing Fractions We all love Math Antics, am I right? 😉 Bonus: Here’s a Review on Converting Fractions! Have questions? Drop a comment below!

3.3 Adding and Subtracting Using Fraction Notation
If you saw the previous post, you might have noticed that some of the videos were adding fractions. While adding/subtracting fractions may seem hard, it’s quite useful to master (albeit annoying to calculate) 🙂 Adding/Subtracting Fractions Converting Fractions Have any questions?

Here is a quick review of polynomials Shape of polynomial graphs End behaviour of polynomial functions Degree and leading coefficient of polynomial functions Zeros of a polynomial function Multiplicity of a polynomial Overview of everything introduced in this section If you…
3.3 Linear Equations
Definitions: Linear Equation: any equation of the form ax+by = c Equations: a mathematical statement that two expressions are equal (ex: y=2) Expressions: a collection of numbers, variables and operation signs (ex: 2x-3) Determining if an Ordered Pair is a Solution to the Equation How to Graph a Linear Equation Linear Equation Word Problems If…
3.2 Functions
💡 Tip = for every value of the domain (x-value) there’s one, and only one, value for the range (y-value) Writing functions is pretty simple, once you get the hang of it. Determining a Function using Various Methods Got any questions? Drop them in the comments below!
