Bonjour
Pyramide somme :
……….| A |
…….| -9 | B |
….| -2 | C | 10 |
-2 + C = -9
C = -9 + 2 = -7
B = -7 + 10 = 3
A = -9 + 3 = -6
……….| -6 |
…….| -9 | 3 |
….| -2 | -7 | 10 |
-6 + B = 4
B = 4 + 6 = 10
8 + C = -6
C = -6 - 8 = -14
-14 + D = 10
D = 10 + 14 = 24
-15 + E = 8
E = 8 + 15 = 23
23 + F = -14
F = -14 - 23 = -37
-37 + G = 24
G = 24 + 37 = 61
………….. | 4 |
………..| -6 | 10 |
……..| 8 | -14 | 24 |
….| -15 | 23 | -37 | 61 |
Pyramide différence :
……….| A |
…….| -9 | B |
….| -2 | C | 10 |
-2 - C = -9
C = 9 - 2 = 7
B = 7 - 10 = -3
A = -9 - (-3) = -9 + 3 = -6
……….| -6 |
…….| -9 | -3 |
….| -2 | 7 | 10 |
………….. | 4 |
………..| -6 | B |
……..| 8 | C | D |
..| -15 | E | F | G |
4 = -6 - B
B = -6 - 4 = -10
-6 = 8 - C
C = 8 + 6 = 14
-10 = 14 - D
D = 14 + 10 = 24
8 = -15 - E
E = -15 - 8 = -23
14 = -23 - F
F = -23 - 14 = -37
24 = -37 - G
G = -37 - 24 = -61
………….. | 4 |
………..| -6 | -10 |
……..| 8 | 14 | 24 |
..| -15 | -23 | -37 | -61 |
