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
2 + 2 x 5 x 6 x 8 x 7 is the algorithm for that
92 = (9 x 10) + (2 x 1)873 = (8 x 100) + (7 x 10) + (3 x 1)
what is 5(x-5) plus 6 expanded and simplified
The expanded form of 55 is: (5 x 10) + (5 x 1)
Expanded Notation of 2155 = (2 x 1000) + (1 x 100) + (5 x 10) + (5 x 1).Expanded Exponential Notation of 2155 = (2 x 103) + (1 x 102) + (5 x 101) + (5 x 100).
9 squared (or 92) = 9 x 9
The expanded form of 50,156 is (5 x 10000) + (0 x 1000) + (1 x 100) + (5 x 10) + (6 x 1)
53 = 125125 in expanded notation is: (1 x 100) + (2 x 10) + (5 x 1)
Expanded Notation of 525 = (5 x 102) + (2 x 101) + (5 x 100).
Expanded Notation of 352 = (3 x 100) + (5 x 10) + (2 x 1)
Expanded Notation of 125 = (1 x 100) + (2 x 10) + (5 x 1)
