I'm aware of the axioms of real numbers, the constructions of real number using the rational numbers (Cauchy sequence and Dedekind cut). But I can't relate the arithmetic of irrational numbers to real world usage.
I can think the negative and positive irrational numbers to represent (measurement of) real life quantities that satisfy the axioms. This is similar to relating positive and negative rational numbers to real world usage.
However, I can't do so for multiplication of irrational numbers. Multplication of rational numbers takes the usual intepretation of "(a out of b) of something".
Any thoughts?
