Bonjour
Recopier et compléter la pyramide ci-dessous en appliquant le modèle ci- contre
…………..| A |
………..| B | C |
..….| D | -15 | E |
….| -8 | 2 | F | 9 |
D = -8 + 2 = -6
2 + F = -15
F = -15 - 2 = -17
E = -17 + 9 = -8
B = -6 - 15 = -21
C = -15 - 8 = -23
A = -21 - 23 = -44
………..| -44 |
……..| -21 | -23 |
..….| -6 | -15 | -8 |
….| -8 | 2 | -17 | 9 |
