Here is a twisting math resolution for you guys:

 

1+1=1 so 1+1=3 (we can also say that 1=2=3)

 

and this is why (the bold parts are the changes that occured):

 

(a+b)(a-b) = a² - ab + ba - b²

(a+b)(a-b) = a² - b²

_Now divide each side by (a-b), we have:

[(a+b)(a-b)]/(a-b) = (a² - b²)/ (a-b)

_We now have:

(a+b) = (a² - b²) / (a-b)

_Let us suggest that: a = b = 1

which gives us:

1+1 = (1-1) / (1-1)

_There is the same terme above and under the division so it is equal 1

so we have:

1+1 = 1

_add one at each side:

1+1+1 = 1+1

3 = 1 + 1

 

There you go!

(we can also conclude that 2 + 2 = 5 and etc. Also we can show that 1=2=3=4=5=etc)

Any comments?

Um, you can "prove" almost anything if you sneak a divide by zero in there. There are so many bogus proofs that use this that it can be called "a really old joke" in math circles. I actually seem to recall us having this discussion here a little while ago (although it might be somewhere else I was thinking about). I remember the first time I saw something like this. It WAS actually pretty freaky smile.gif

If it passed the vertical line more then once, that would make it a parabola, and therefore quadratic, and not a linear equation.

 

I hate quadratic equations... not cause they don't make sense, or they're hard... They're just the same thing over and over again... No challenge.

I'm doing Enriched Grade 11 Math, and Advanced Enriched Grade 12 Math in the same semester so I can do my Calculus and AP Math next year... but we haven't started any serious algebra yet, so I'm lost, but wanted to feel cool and in with the math geeks, so I posted some random fact that's true... Shows how great my life is... I'm reaching to the Math geeks for acceptance. biggrin.gif

I represent the silent multitude of people who have no clear idea what you 'math geeks' have been talking about. wink.gif

 

I thought a 'vertical line test' was that embarrassing thing the cops make you do on the side of the road with everyone staring at you as they drive past...

Yeah, I was waiting till someone mentioned it befor discussing it:

what if you do not suppose a zero but the term (1-1), therefor the rule can be applied, can it?
