hyperreal numbers

Wow, I've heard about hyperreal numbers, they're cool. They are an extension of the real numbers, but infinty and infinetisimally small are elemnts of the hypereals. That's cool. Then you can actually find out what the square root of inifinty is (it's still infinty BTW). Also makes calculus easier...:) :) Why don't they…

A great intro tohyperreals is here: http://mathforum.org/dr.math/faq/analysis_hyperreals.html

I love hyperreal numbers... (spot the maths nerd)
