1+1

1+1 = -2
Because:

1+1 = sqrt((1+1)^2)
sqrt((1+1)^2) = sqrt(2^2)
sqrt(2^2) = sqrt(4)
sqrt(4) = sqrt(-2^2)
sqrt(-2^2) = -2

This is because:

-2^2 = 4

1+1 is sooo not two. it's -2!

Why in the living fuck did you search for '1' on Urban Dictionary? Did you have nothing else to do? Did you search up something inappropriate and your parent/guardian walked in? Either way I think it's pretty weird.

Wtf i can't believe you just searched for '1' on urban dictionary

Great, you looked up the very first number on the keyboard. You must have no life.

1+1=2, if you are too dumb to even know this

$1

A buck. (Not a deer.) (Or a moose.)

One dollar.

Some stupidly named variable in Perl or BASIC or some other useless, loosely typed programming language.

"Gimmee $1, I need a Snickers"

if ($1=="stupid") {
print "Who is stupid enough to use \$\1 as a variable name? Perl sucks\n";
}
