Solve simultaneous equations using the elimination method.
The steps are as follows:
The Elimination Method
Step 1: Multiply each equation by a number so that the two equations have the same coefficient for a selected variable.
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation to get the value of your first variable.
Step 4: Substitute into either Equation 1 or Equation 2 above and solve for the second variable.

Permutations and Combinations tell us the number of different arrangements of items or numbers that can occur. In this lesson we look at the counting principle - a fast method of counting the number of various arrangements through multiplication.
In this video we also use combinations and permutation counting principles to answer some of the big questions of life - how many different outfit combinations do you have, how many lotto permutations are there, why do they call the tecmath the Count?

Fractions are parts of numbers. In this introduction to fractions we look at the parts of a fraction - the numerator and the denominator, as well as proper fractions, improper fractions and mixed numbers and how these relate to each other.

The twelve times table trick fast and easy to apply - and it will leave you able to multiply any number by twelve rapidly!
It is similar to an eleven times table trick we have looked at earlier - https://www.youtube.com/watch?v=_HrHUUWtsbE
Just follow these simple rules - for the number being multiplied, double each number in turn and add its neighbour (to the right). Some carrying may be involved but it is easy to handle. This math trick will amaze you!
When you try these out for yourself, write the figures spaced apart, and as you go through answering the question place each part of the answer directly below the digit the answer was derived from. This will help you avoid errors when getting the answer.
In this particualr case of multiplication it is important because you need to easily be able to identify the 'number' and the 'neighbour'.
This method works for all multiplication of twelve. It is not meant as a substitute for knowing your times table, rather, it is meant to allow you to expand your mathematical capabilities and to recognise patterns.

Dividing decimals is easy, just divide like usual - and work out the number of decimal places as follows:
The number of decimal places in the answer = number of decimal places in the item being divided - number of decimal places in the dividing number....
e.g. 123.963 (3) / 0.3 (1) = 413.21 (3 - 1 = 2) where decimal places are shown in brackets.
