Respected All Members,

Here is a math trick so unbelievable that it will stump you.

1. Grab a calculator. (You won't be able to do this one in your head)

2. Key in the first six digits of your mobile number

3. Multiply by 80

5. Multiply by 250

8. Subtract 250

9. Divide number by 2

Thank You!!

Wooo, number manipulation!

It's fairly simple to see how this works.

 Spoiler (Rollover to View): Say for example your phone number is 123-456-7890 This translates to 123456 as your first number. So the equation presented is: (((123456 * 80) + 1) * 250 + 7890 + 7890 - 250) / 2 = 1234567890 Let's simplify this a bit, shall we? and sorry, code show's through spoiler tag (((123456 * 80) +1) * 250 - 250 + 7890 * 2) / 2 = 1234567890 (A little rearranging... multiply by 2 instead of adding twice) ((123456 * 80) * 250 + 250 - 250 + 7890 * 2) / 2 = 1234567890 (250 * 1 is 250, so we can get rid of these...) (123456 * 20000 + 7890 * 2) / 2 = 1234567890 (80 * 250 is 20000) (123456 * 20000) / 2 + (7890 * 2) / 2 = 1234567890 (get rid of those pesky 2s...) 123456 * 10000 + 7890 = 1234567890 (almost there...) 1234560000 + 7890 = 1234567890 (almost...) 1234567890 = 1234567890 (and done, all that to put four zeroes on the end of the first six numbers, then replace them with the last four numbers)

So there you go.

**EDIT** Bah, fixed, what I get for doing insomniac math equations.

And in the spirit of this, how about the first mathamagic trick I learned ever?!?

Oh come on, it's not gonna be that bad...

Think of a number, any number at all.

Got it?

Okay, now multiply that number by 2.

Now, add 8 to that number.

Okay, now divide that number in half.

Now, take that number and subtract your original number from it.

Okay, got it? Don't tell anyone...

1=a, 2=b, 3=c and so on...

Now, think of a country in Europe that starts with that letter.

Now, take the second letter in that country's name and think of an animal in Africa that starts with that letter.

Okay, now this part is gonna be reeeeally tricky...

Take your last number and think of a color with that many letters.

Got it?

Love the quote, Citizen Kane!
