By setting up an equation where you eventually divide both sides by a term that equals zero—such as (a-b) where a=b—you can “cancel out” numbers to show that 4=5. However, because division by zero is undefined in mathematics, the proof is considered a fallacy.

Start with: -20 = -20 Which is the same as: 16-36 = 25-45 Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5 Add 81/4 to both si
- arithmetic - What's wrong with this fake proof that $2+2=5$? - Mathematics Stack Exchange
Namely, $\sqrt{x}$ and $-\sqrt{x}$. This is because $x^2=(-x)^2$. When you do the incorrect step in your proof, you're taking the square root of both sides but really, you should be taking either $\sqrt{x}$ or $-\sqrt{x}$. So, in fact, it would be correct to say that $\left(4-\frac92\right)=-\sqrt{\left(5-\frac92\right)^2}=-\left(5-\frac92\right)$.

Many people pointed out that two animals can become three through reproduction (1+1=3, or 1+1=1, depending on your parameters), or that two machines could become three machines if you had some spare parts from each machine and a little elbow grease. Others pointed out that 2.3 rounds down to 2, but 2.3+2.3 rounds up to 5, making it possible through a certain filter that 2+2=5.
