### The Beauty Of Mathematics

That's good stuff Sig.

Regards the math, here's a good one for you to amaze friends with.

Have them give you a 4 digit number.
Suppose it 4857.

Take that, write it down, and on another piece of paper, subtract 2 and take the 2 you subtracted and stick it on the left making a 5 digit number.
So 4857 - 2 = 4855

On another sheet of paper, write:
24855, fold it and hand it to them for safe keeping.

Have them give you another 4 digit number, suppose 3381, write it below the 4857, as so

4857
3381

Now it's your turn. Subtract 3381 (or whatever they gave you) from 9999 and write the result below the 2nd number like so

4857
3381
6618

Have them give you another 4 digit #, suppose 5724, write it below in the 4th spot

4857
3381
6618
5724

subtract that number form 9999 and write the result

4857
3381
6618
5724
4275
__________

They will equal the 5 digit # you wrote down and handed to them. Every time.
