Can you scientifically prove to me that 2+2= 4?

I'll mathematically prove it to you.

• This is easily demonstrated

• Add to both sides

• This can be factored

• Take the square root of both sides

• Now add to both sides

 

Using properties of equality, we can makes this 2+2=5. Wait...

Square roots have a positive and negative answer.  You can't simply make the sign positive.  You'll notice one = -1/2 and the other 1/2.  Plus or minus makes them equal. ;).
