simple proof make your mind mad

Start with: 20 = 20
Which is the same as: 1636 = 2545
Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5
Add 81/4 to both sides: (2+2) 2 (9 X (2+2) + 81/4 = 52) 9 X 5 + 81/4
Rearrange the terms: ({2+2}) 9/2) 2 = (59/2) 2
Ergo: 2+2  9/2 = 5
Hence: 2 + 2 = 5
See... simple, isn't it?

Your equations as written don't make much sense to me. Could you clarify them a bit?
Usually I've found that similar problems are due to division by 0, but again, I can't follow your math to see if this is the case here.

20=20
1636=2545
4^236 = 5^245
4^236 = 5^245
4^22.4.9/2 = 5^22.5.9/2
4^22.4.9/2 +(9/2)^2 = 5^22.5.9/2 +(9/2)^2
[4(9/2)]^2 = [5(9/2)]^2
4(9/2) = 5(9/2)
4 = 5
2+2 = 5
I have made a picture for the correct formatting of the quotations above.
Between step 5 and 6 the following is applied a^2 + 2ab + b^2 = (a + b)^2

Each number system has exactly 10 different digits.

This is actually a common trick (although not as common as divide by zero). The trick relies on the fact that the square root has a positive *and* negative result  and basically obfuscates the fact that they are taking the positive number in one case, and the negative number in the other.

I'm curious...
We seem to see a handful of these "proofs" each year. Does anyone here still believe there are simple algebraic ways to prove that two unequal constants are equal?
I'll admit that sometimes it's a fun challenge to determine which one is the invalid step in a new "proof". I'm with Arun... this kind of thing may deserve a or maybe a , but I certainly don't think it deserves a , as some have gotten.
