Nice one:
111,111,111  x  111,111,111 = 12,345,678,987,654,321

Trapeze:


     3 x 37 = 111
6 x 37 = 222
9 x 37 = 333
12 x 37 = 444
15 x 37 = 555
18 x 37 = 666
21 x 37 = 777
24 x 37 = 888
27 x 37 = 999

                                    0x 9 + 1 = 1
                           
1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111

            123456789 x 9+10 = 1111111111

another Trapeze:
                      
      1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

and another one:

                                   0x 9 + 8 = 8
                                  9 x 9 + 7 =
88
                                98 x 9 + 6 =
888 
                              987 x 9 + 5 =
8888
                            9876 x 9 + 4 =
88888
                          98765 x 9 + 3 =
888888
                        987654 x 9 + 2 =
8888888
9876543 x 9 + 1 =
88888888

                    98765432 x 9 + 0 =
888888888
                  987654321 x 9 –  1 =
8888888888
                9876543210 x 9 –  2 =
88888888888 

願大家都  發發
