It is widely used both in mathematics and our everyday life, for example, it is Theoretically used in the process of analytic geometry and algebraic expression, and practically used in engineering project , constructing and economic management. So how to pute Determinants are very important. However, in most case, the puting of Determinants especially N Order Determinants is always be a time consuming and plicated process, not to mention when we are in the middle of an exam when our mind is too nervous to think clearly. This paper works on several kinds of special N order determinants and sort out some typical ways to work out Determinants according to their type. The Author pile this paper in hoping of concluding some feasible ways to pute Determinants so that make the process easier and more concise.Key words: N Order Determinant。 Determinant。 Computational Method21
