It is supposed to represent a rotated 5, which has not (yet !) any asigned meaning in math.
If x is arbitrarily close to 8, then x-8 is arbitrarily close to zero, and \frac{1}{x-8} is arbitrarily large, that is \frac{1}{x-8} goes to ininity, which is represented by \infty. Apparently the guy did not know what \infty meant, so he interpreted the sign as a rotated eight. Naturally for him then \frac{1}{x-5} must go to rotated 5 when x is arbitrarily close to five. As you can see of course, the answer was the same : \frac{1}{x-5} must go to \infty too when x is close to five...

Researchers in Fairbanks Alaska announced last week that they have discovered a superconductor which will operate at room temperature.
