#### MathsCasts: Simplifying Algebraic Fractions with Cancellation Part 1

(Swinburne Commons, 2013)

We look at how to simplify algebraic fractions when there is a number and/ or power of a letter that is common to all terms on the numerator and denominator, thus allowing us to simplify the original fraction by cancelling ...

#### MathsCasts: Adding and Subtracting Example

(Swinburne Commons, 2013)

We look at several examples of adding and subtracting positive and negative numbers, including examples where there are two immediately adjacent signs (e.g. two negative signs).

#### MathsCasts: Graphing Factorised Polynomial Functions

(Swinburne Commons, 2013)

Looks at how linear factors to odd and even powers can help in sketching polynomial functions that can be factorised into all linear factors.

#### MathsCasts: Prime Factors

(Swinburne Commons, 2013)

We look at how to factorize a number into a product of prime factors, with several examples.

#### MathsCasts: Inverse Functions: Example 1

(Swinburne Commons, 2013)

Gives the definition and conditions for the inverse of a function to exist, and then applies this to an example the case of finding the inverse of a one-to-one function.

#### MathsCasts: Addition of Binary Numbers

(Swinburne Commons, 2013)

In this recording, addition of binary numbers is demonstrated, with reference to a specific example.

#### MathsCasts: What's Wrong? Cancellation of Algebraic Fractions

(Swinburne Commons, 2013)

We look at an example of a case where an algebraic fraction is actually already in its simplest form, and some of the common errors people make in trying to 'cancel' terms in this case.

#### MathsCasts: Integrating Rational Functions Part 1

(Swinburne Commons, 2013)

This recording demonstrates how to integrate rational functions where the numerator is a constant and the denominator is a linear function. Integration by substitution is used.

#### MathsCasts: Transposition with Required Variable in the Denominator

(Swinburne Commons, 2013)

In this recording we look at how to rearrange a formula where the letter that we want to make the subject is in the denominator. That is, we look how to make f the subject when presented with an expression of the form a/b ...

#### MathsCasts: Adding and Subtracting Surds

(Swinburne Commons, 2013)

We look at cases when we can add and subtract surds- namely when terms can be re-written with the same number under the square root sign. Two examples are given- in the second example the surds need to be simplified before ...
