Dust off those high school math books and get yourself a calculator that can handle a lot of digits. This cache is an equal opportunity for all denominators (and numerators). In the fractions presented there are NO addition or subtraction operations. Everything is either a division or multiplication. A 'dot' between two fractions means multiply.
