6 x 7 Break up the 7	6 x 5 = 30 6 x 2 = 12 30 + 12 = 42
3 x 8	8 x 2 = 16 8 x 1 = 8 16 + 8 = 24
9 x 3	9 x 2 = 18 9 x 1 = 9 18 + 9 = 27
6 x 4	6 x 2 = 12 6 x 2 = 12 12 + 12 = 24
6 x 8	6 x 2 = 12               6 x 4 = 24 6 x 2 = 12               6 x 4 = 24 6 x 2 = 12     Or 6 x 2 = 12   48
9 x 6	9 x 3 = 27   or 9 x 2 = 18 9 x 3 =  27                         9 x 2 = 18                          9 x 2 = 18                           Then  just do that 6 times 54
4 x 7	7 x 2 = 14 7 x 2 = 14 28
4 x 9	9 x 2 = 18 9x 2 = 18 18 + 18 = 36
7 x 8	8 x 5 = 40 8 x 2 = 16 40 + 16 = 56
9 x 7	9 x 5 = 45 9 x 2 = 18 45 + 18 = 63
7 x 3	7 x 2 = 14 7 x 1 = 7 14 + 7 = 21
