Okay, so I've been taking this new class at school at the start
of a new semester, and it's really cool. Basically we work for the
school's newsletter, learn how reporters write their
notes/articles, how they can talk so fast and calm on TV, and how
to rate/review different things, such as cafes or video gams! So,
this class inspired me to create my own personal newsletter which I
will post on each of the Wiki's I'm a member at, called "Harley's
Hub!". Featured in this newsletter will be stories on different
Wikis, ratings of different Wikis, polls about different Wikis, and
stuff like that. BUT, here's the good stuff. You may submit your
Wiki to either get a lead story, a spot in the review section, or a
slot in the poll section! Just tel…

I stubled across 3 false proofs, see if you can find the
errors.

X=Y

X^2=X*Y

X^2-Y^2=X*Y-Y^2

(X+Y)*(X-Y)=Y*(X-Y)

X+Y=Y

2Y=Y

2=1

X=0.99999...

10X=9.99999...

10X-X=9.99999...-X

9X=9

X=1

0.99999...=1

This one is a word problem. Imagine a square with sides of 4,
and therefore a perimiter of 16. Cut corners, and the perimiter
stays the same. See below for a visual.

The perimeter of the above shape is equal to the perimeter of the
shape below. (_ equals negative space)
