His classmates were labouring with elementary algebra.

他的同学们正在绞尽脑汁地演算初等代数。

Let G be an infinite group. If G has a normal elementary abelian subgroup, then G is irrecognizable.

G无限群,若G存在正规初等交换子群,则G不可分辨的.

Based on some basic theorems in theory of numbers this program takes advantage of probabilistic algorithm to test a large number for primality.

基于初等数中的一些基本定理,本程序利用概率算法,快速判定一个大数数。
