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

um, 4 - 6 = -2

and 1 - 3 = -2

so how are these inequal? tarheel actually got to the crux of this issue, which is that square roots have both positive and negative answers. This was further disguised by leaving each root as a positive integer minus a fraction of a value greater than one.
