12 x 13 = 13 x 10 + 13 x 2 = 130 + 26 = 156
66 x 11 = 66 x 10 + 66 x 1 = 660 + 66 = 726
45 x 22 = 45 x 20 + 45 x 2 = 900 + 90 = 990
123 x 23 = 123 x 20 + 123 x 3 = 2460 + 369 = 2829
100 + 45 = 145
66 x 11 = 66 x 10 + 66 x 1 = 660 + 66 = 726
45 x 22 = 45 x 20 + 45 x 2 = 900 + 90 = 990
123 x 23 = 123 x 20 + 123 x 3 = 2460 + 369 = 2829
100 + 45 = 145
