Stolen from another webpage (link at the bottom). I'll assume since you asked that you know that this "proof" is no such thing.

(1) Let x = 2+2

(2) Multiply both sides by (x - 1): x(x - 1) = (2 + 2)(x - 1)

(3) Distribute: x² - x = 2x + 2x - 2 - 2 = 4x - 4

(4) Subtract 3x from both sides: x² - x - 3x or x² - 4x = 4x - 3x - 4 or x - 4

(5) Multiply both sides by (x - 5): (x - 5)(x² - 4x) = (x - 5)(x - 4)

(6) Distribute: x³ - 9x² + 20x = x² - 9x + 20

(7) Factor: x(x - 4)(x - 5) = (x - 4)(x - 5)

(8) Divide both sides by (x - 5): x² - 5x = x - 5

(9) Add 4x to both sides: x² - 5x + 4x or x² - x = x - 5 + 4x or 5x - 5

(10) Factor: x(x - 1) = 5(x - 1)

(11) Divide both sides by (x-1): x = 5

And we started with x = 2 + 2, therefore 2 + 2 = 5

under no circumstances can 2+2=5..it is not an equation that is possible

2 + 2 can't equal 5.
