Evil maths

I saw this interesting video in my friends blog, so i decided to put it in ours.No harm was intended upon the posting of this video.

Below is a written version of the video:

now for something useful..... Someone posted that since there is a square root, we have to reject the negative. so by adding the absolute sign into our equation, we can reject the negative. so our equation becomes:"Grils = l [squareroot(evil)]squared l"(please write this down so you can see it more clearly). Note: l-2l is 2. we call 2 the absolute value of -2. After simplifying our equation, we get grils equals l evil l. which in written form, is absolute value of evil, so girls equals ABSOLUTE EVIL.

But before i got the joke, i realised, that there is actually no need to reject negative( yes here is the useful part). because, anything squared must be a positive number. We may argue that the equation could be written as: "squareroot of l (evil2) l ". thus, square root of evil squared has the need to reject negative. so we get "Girls = square root of absolute 2 (-2 or 2)" thus after we simplify the whole thing, we still get girls = absolute evil.

but again, when we do not add the absolute, the eqation still stands, as "square root of -evil2" will not be a integer, as only a positve number can be squared.so sadly, the absolute joke doesnt work.
