兩組算式結構上是一樣的,窮舉法可以找到所有這些可能的答案。
14 = 05 + 9 76 = 38 * 2
14 = 05 + 9 78 = 26 * 3
14 = 09 + 5 76 = 38 * 2
14 = 09 + 5 78 = 26 * 3
23 = 14 + 9 56 = 07 * 8
23 = 14 + 9 56 = 08 * 7
23 = 19 + 4 56 = 07 * 8
23 = 19 + 4 56 = 08 * 7
25 = 17 + 8 36 = 04 * 9
25 = 17 + 8 36 = 09 * 4
25 = 18 + 7 36 = 04 * 9
25 = 18 + 7 36 = 09 * 4
37 = 28 + 9 60 = 15 * 4
37 = 29 + 8 60 = 15 * 4
41 = 32 + 9 56 = 07 * 8
41 = 32 + 9 56 = 08 * 7
41 = 35 + 6 72 = 08 * 9
41 = 35 + 6 72 = 09 * 8
41 = 36 + 5 72 = 08 * 9
41 = 36 + 5 72 = 09 * 8
41 = 39 + 2 56 = 07 * 8
41 = 39 + 2 56 = 08 * 7
47 = 38 + 9 60 = 12 * 5
47 = 39 + 8 60 = 12
