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...

Nice parlor trick, but, you fail for injecting non-equal numbers into an equation in step one, i guess this works well among your fellow 7th graders though :P
