    Định nghĩa hai ma trận A và B

    A = [[1, 1], [2, 2]] B = [[3, 2], [1, 4]]

    Tính tổng hai ma trận

    def add_matrices(A, B): result = [[0, 0], [0, 0]] for i in range(len(A)): for j in range(len(A[0])): result[i][j] = A[i][j] + B[i][j] return result

    Tính hiệu hai ma trận

    def subtract_matrices(A, B): result = [[0, 0], [0, 0]] for i in range(len(A)): for j in range(len(A[0])): result[i][j] = A[i][j] - B[i][j] return result

    Tính tích hai ma trận

    def multiply_matrices(A, B): result = [[0, 0], [0, 0]] for i in range(len(A)): for j in range(len(B[0])): for k in range(len(B)): result[i][j] += A[i][k] * B[k][j] return result

    In kết quả

    print("Tổng A + B:") print(addmatrices(A, B)) print("Hiệu A - B:") print(subtractmatrices(A, B)) print("Tích A x B:") print(multiply_matrices(A, B))
