| Abstract: | Hua Heng-fang (1833-1902) was a famous mathematician in the end of Qing Dynasty. In. his book Ji Jiao Shu (A Method of Finite Difference, 1870') Hua gave a formula of sum of powers of natural numbers using Hua's numbers. The study on sum of powers of natural numbers has a long history and a common interest today. Hua's numbers have good qualities but are not known by many mathematicians. Awaked by Hua's method only change one sign in Hua's definition and get a new formula of sum of powers of integer in this paper. This formula is very simple, and has some combinatorial significance. A box-taking and boll-putting combinatorial model is established also. |
