How to easily multiply any number by twelve
 
03:53
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.

Fraction of amount and percentage of amount
 
03:33
To work out the fraction of an amount, first of all it is essential to convert the fraction to a decimal. To do this divide the numerator (top number) by the denominator (bottom number). eg - 1/5 = 0.2 Then times this answer by the amount you wish to find a fraction of. e.g 1/5 of 20 = 0.2 x 20 = 4 To work out the percentage of an amount, it is also essential to first convert the percentage to a decimal. To do this move the decimal place left two spaces - eg - 25% = 0.25 Then times this answer by the amount you wish to find apercentage of. e.g 25% of 20 = 0.25 x 20 = 5.

How to square any numbers in your head - fast mental math trick
 
05:25
Learn how you can square large numbers in your head - instantly! This easy to learn technique will have you calculating the square of numbers up to 100 - without the need for a calculator. The trick is easy - first we find the distance from the number being squared to the nearest tens number. Say for example we are trying to find the square of 23 - the nearest tens number is 20, which is 3 away from 23. So 3 is our result! We use this number to find the square - by taking this number from the number being squared (23 - 3 = 20) and then adding this number to the number being squared (23 + 3 = 26). We easily multiply these two numbers (20 x 26 = 520). To this we add our distance number squared (3 x 3 = 9). So we add 9 to 520...our answer is 529. Love the math! The old math is dead! Long live the math!
