Expanded notation of 64 = (6 x 10) + (4 x 1)
64 = (6 x 10) + (4 x 1)
64 = (6 x 10) + (4 x 1)
I'm not entirely sure I know what you mean by "expanded algorithm" but here is a guess: 31 * 19 = (13 * 9)+(31 * 10) = 117 + 310 = 427
964 = (9 x 100) + (6 x 10) + (4 x 1)

92/2 = 46 46*10 = 460.
33 = 2726 = 647 x 13 = 91
964 = (9 x 100) + (6 x 10) + (4 x 1)
4 to the 3rd power = 64 = (6 x 10) + (4 x 1)
0.64 = (0 x 1) + (6/10) + (4/100)
2 + 2 x 5 x 6 x 8 x 7 is the algorithm for that
91 x 91 = 8281
1 x 91, 7 x 13, 13 x 7, 91 x 1 = 91
