**Multiplying any number by 5**

SO, if, say, you had the number 8,600 (the amount of money in your bank account right now??) and you wanted to multiply it by 5, simply do this:

Divide 8600 by 2 (easy!), which gives you 4300, and then just move the decimal point to the right, giving you 43000.

You can do this very quickly in your head with just about any number, because dividing by two is usually pretty easy. And moving the decimal point is even easier!

Just for fun, try multiplying 8600 by 5 in your head the traditional way. Well...it wasn't very fun, was it?

Try multiplying a few more numbers by 5 in your head this way, until you can build up some magic-like speed. Here, use some of my numbers, or if you feel adventurous, come up with some of your own!

Don't let those odd numbers trip you up. You will end up with "something.5" when you divide by two, but after moving the decimal point over one space you get a number ending in 5. If it helps, just remember that all odd numbers multiplied by 5 end in 5!

**Dividing any number by 5**

This time if you want to divide the number 8,600 by 5, just do this:

Multiply 8600 by 2 (just double it - still easy!), which gives you 17200, and then just move the decimal point to the left, giving you 1720.

Now try it the old way...I don't know about you, but doing that makes my brain hurt....

When you divide any number by 5 that doesn't end in a 5 or a zero, you will end up with a decimal point. Mental arithmetic involving decimal points usually brings on headaches of various potencies with people, but handling decimals this way is a piece of cake. It actually will enhance the magical aura surrounding you.... Watch this thought process at work:

123 ÷ 5 = [ Multiply 123 by 2 (double it), which is 246, and then move the decimal point to the left, which is 24.6 !]

So the answer is 24.6. Doesn't 24.6 sound impressive??

Ok. Now to get the speed up. Try some of these:
