W piramidach dwie liczby z dołu powinny dać sumę klocka u góry. 

W takim razie:

88 - 36 = 52, bo 36 + 52 = 88

36 - 19 = 17, bo 19 + 17 = 36

52 - 19 = 33, bo 33 + 19 = 52

19 - 18 = 1, bo 18 + 1 = 19

17 - 1 = 16, bo 16 + 1 = 17

33 - 18 = 15, bo 15 + 18 = 33

---

Podobnie obliczamy dla kolejnej piramidy:

31 + 13 = 44

46 - 13 = 33, bo 13 +33 = 46

44 + 46 = 90

33 - 25 = 8, bo 8 +25 = 33

13 - 8 = 5, bo 5 + 8 = 13

oraz

31 - 5 = 26, bo 26 + 5 = 31

---

78 - 32 = 46, bo 46 + 32 = 78

26 - 12 = 14, bo 14 + 12 = 26

46 - 26 = 20, bo 20 + 26 = 46

32 - 20 = 12, bo 20 + 12 = 32

20 - 12 = 8, bo 12 + 8 = 20
