Mathematical wrongs

Post your favorite mathematical wrongs.

My personal favorite is 53,670,123.55 x 45,921 = 21.5

 

1 +1=3

 

Excellent choice.

 

You can right all of those wrongs with some mathemagic.

 

Can you right my original wrong with mathematics?

 

a^2 + b^2 = c^69

 

The square root of any even number over 7 will always end in .73

 

No but I can using algebra.

 

Sorry, only mathematics are allowed.

 

Too bad bird.

 

That are the rules of this thread, not much one can do about it.
However, you can always start a new thread that includes algebra and mathemagic as well.

 

I'm well aware that I can choose to start a new thread but I'm exercising my freedom not to.

 

2 x wrong=right

 

pi=3.15

 

there is nothing wrong with mathematics that can not be fixed by what is right with mathematics.

 

pi=R2

Actually cornbread R square, pie R round.

 

that made me grin....

my favorite though is

Pi = 3.... just 3...

 

7 divided by 0 equals 11.

 

you know, despite my complete lack of mathematical knowledge, this thread had funnier responses than i expected. i give it a 5/10.

 

you mean a 100?

as you know 5/10 = 100
