Zapisujemy działania:
37 + 7 = 44
46 + 7 = 53
63 + 7 = 70
37 + 5 = 42
46 + 5 = 51
60 - 5 = 55 (tutaj wpisujemy w liczbę w pomarańczowe pole, więc możemy też obliczyć: 55 + 7 = 62)
63 + 5 = 68
71 - 63 = 8
37 + 8 = 45
46 + 8 = 54
55 + 8 = 63
37 + 9 = 46
46 + 9 = 55
55 + 9 = 64
63 + 9 = 72
Uzupełniamy więc tabelę:
+ | 37 | 46 | 55 | 63 |
7 | 44 | 53 | 62 | 70 |
5 | 42 | 51 | 60 | 68 |
8 | 45 | 54 | 63 | 70 |
9 | 46 | 55 | 64 | 72 |
72 - 6 = 66
91 - 6 = 85
55 - 6 = 49
55 - 46 = 9
54 + 9 = 63
63 - 6 = 57
72 - 9 = 63
91 - 9 = 82
91 - 84 = 7
72 - 7 = 65
63 - 7 = 56
55 - 7 = 48
91 - 8 = 83
63 - 8 = 55
55 - 8 = 47
Uzupełniamy tabelę:
- | 72 | 91 | 63 | 55 |
6 | 66 | 85 | 57 | 49 |
9 | 63 | 82 | 54 | 46 |
7 | 65 | 84 | 56 | 48 |
8 | 64 | 83 | 55 | 47 |
