| Abstract: | In the calculation or certification of the matrix,see order one matrix as a real number sometimes.However,there is no a strict proof of that in the algebra textbooks.Given the proof of the identity between order one matrix and the real number from the view of the equivalence relation ship. |

| Keywords: | real number a order one matrix(a) equivalence relation ship equivalence class |
