        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
 


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