### More Tricks!

**Here are some more mental Math tricks for you to try ....**

**Quick Square -**Did you know that there is a quick way of squaring a two digit number which ends in 5? Just multiply the first digit by that number +1 and stick a 25 after your product and there's your answer ...^^

Example:

Q. What is 35 squared?

A. 3x4=12

.....now stick on the 25

.....the answer is

**1225**

**Times Eleven -**The eleven times table has always been very easy to learn up to 9 x 11. Here's a way of multiplying large numbers by 11 too:

Example:

Q. What is 324 x 11 ?

A. Write down the first digit... 3

.......Add the first and second digits .. 3 + 2 = 5

.......Add the second and third digits .. 2 + 4 = 6

.......Write down the last digit ........ 4

The answer is

**3564**

**Multiplying by Four -**Doubling a number is quite easy. We learn doubles as some of our first number facts. So multiplying by four is easily achieved by doubling, then doubling again.

Example:

Q. What is 742 x 4?

A. 742 x 2 = 1484

.....1484 x 2 = 2968

The answer is

**2968**
