Infinity?

Sounds like Greek to you?

Human Language:
As the value of x goes to 8 (starting from 0, then 0.0000000001 etc.. eventually 8), the denominator will eventually go to 0. When that happens, at Sec 4 level, teachers say "no such thing!" but at tertiary level, it really means that the entire fraction goes towards infinity... a very, very big number..

So what's the joke, you may ask??? Simple, the infinity symbol resembles an 8 that has been rotated 90 degrees (clockwise or anti, does it matter??) so the student assumed it was an 8 and did the same for the other question. Lame!!
