' His most celebrated work in pure mathematics, which has proved a starting point for several valuable investigations

 numbers ... In particular it introduced the modern theory of congruences of the tirst and second orders, and to this 

 Gauss reduced indeterminate analysis. In it also he discussed the solution of binomial equations of the form x* = 1,*
