Mathematical anomaly (or is it) 2 = 1
How about this one then, it demonstrates how you can make 2 equal 1 (or does it) Can you spot the error?
If we take two numbers, and call them X and Y,
Lets assume that X = Y
then
X - Y = 0
and,
2X - 2Y = 0
so then,
2X - 2Y = X - Y
another way of doing this would be,
2(X - Y) = 1(X - Y)
If we then cross devide both sides by (X - Y)
we are left with
2 = 1

1/1 = 1
1/0.1 = 10
1/0.01 = 100
-----
1/0.000000001 = 1,000,000,000
So as the number being divided tends towards 0, the value of the equation tends towards infinity.
So there! nerr!
1/0.1 = 10

It is infinity since any number divided by 0.000000000000000000000000001 is huge, so the closer you get to dividing by 0, the closer you get to infinity

Pi, on the other hand is a real number but it's irrational. Infinity isn't even real - fancy that!
