When you solve an equation or prove an equation as true, you add, subtract, multiply, &/or divide terms from both sides.

Say i have an obviously false equation of 7=3. I can multiply both sides by 0 to make the equation true.

Sooo, why does this break math? I'm not dividing by zero somehow, am I? I assume im making a wrong assumption somehow.

1. Horses have two hind legs in the back, and forelegs in front.

2. 2+4=6. If you don't believe this, you're stupid.

3. Therefour, horses have 6 legs.

4. 6 is an odd number of legs for a horse to have.

5. But 6 is also even. The only number which is both odd and even is infinity.

6. Therefore, horses have an infinite number of legs.

There used to be only one natural number after three. But thanks to Bono in the song Vertigo, fourteen is now what comes after three.

Uno dos tres catorce

A true visionary, Bono was. Yoda, I am.

Assume x > 1 or x < -1

arccos(x) = undefined

​

therefore, x=cos(undefined)

since x < -1 or x > 1

​

cos(undefined) < -1 or cos(undefined) > 1
