**THE 11 TIMES TRICK**

We all know the trick wen multiplying by ten - add 0 to end of the number,but did you know there is an equally east trick for multiplying a two digit number by 11?This is it:

Take the original number and imagine a space between the two

digits (in this example we will use 52:

5-2

Now add the Two numbers toether and put them in the middle:

5-(5+2)-2

That is it- You have the answer: 572.

If the numbers in the middle add upto a 2 digit number,just insert the second number and ass 1 to the first:

9-(9+9)-9

(9+1)-8-9

10-8-9

1089- It works every time.

**QUICK SQUARE**

If you need to square a 2 digit number ending in 5,you can do very easily with this trick.Multiply the first digit by itself+1,and put 25 on the end.That is All!

252= (2x(2+1)) & 25

2x3=6

625

**MULTIPLY BY 5**

Most people memorize the 5 times tables very easily,bu

t when you get in to large numbers it gets more complex- o does it?This tick is supe easy.

Take any number,then divide it by 2 (in other words,hal

ve the number).If the result is whole,add a 0 at end.

If it is not,ignore the remainder and add a 5 at the end.it works everytime:

2682x5=(2682/2) & 5 or 0

2682/2=1341(whole number so add 0)

13410

Let's try another:

5887x5

2943.5(fractional number (ignore remainder,add 5)

29435

**MULTIPLY BY 5**

This one is simple-to multiple any number betweem 1 amd 9 by 9 hold both hands in front of you face- drop the finger that corresponds to the number you are multiplying (for example 9x3-drop your third finger)- count the fingers before the

dropped finge (in the case of 9x3 it is 2) then count the numbers after (in this case &)-the answer is 27.

**MULTIPLY BY 4**

This is a very simple trick which appear obvious to s

ome,but to others,it is not.The trick is to simply multiply by two,then multiply by two again:

58x4 = (58x2) = (116) + (116)=232

**CALCULATE A TIP**

If you need to leave a 15% tip,here is the easy way to do it.Work out 10% (Divide the number by 10)-then add that number to half its value and you have yo

ur answer.

15% of $25= (10% of 25) + (10% of 25)/2)

$2.50 + $1.25=$3.75

**TOUGH MULTIPLICATION**

If you have a large number to multiply and one of the num

ber is even,you can easily subdivide to get the answer:

32x125 is the same as:

16x250 is the same as:

8x500 is the same as:

4x1000=4,000
