Les cases de ( a - b + c ) :

1) a - b + c = 9 - (-1) +5

a - b + c = 9 +1 +5

a - b + c = 15

2) a - b + c = 7 - (-6) + (-3)

a - b + c = 7 +6 -3

a - b + c = 13 -3

a - b + c = 10

3) a - b + c = -3 -8 + (-4)

a - b + c = -3 -8 -4

a - b + c = -15

4) a - b + c = -5 - (-2) + 6

a - b + c = -5 +2 +6

a - b + c = -5 +8

a - b + c = +3

Les cases de ( a - b - c ) :

1) a - b - c = 9 - (-1) -5

a - b - c = 9 +1 -5

a - b - c = 5

2) a - b - c = 7 - (-6) - (-3)

a - b - c = 7 +6 +3

a - b - c = 16

3) a - b - c = -3 - 8 - (-4)

a - b - c = -3 -8 +4

a - b - c = -11 +4

a - b - c = -7

4) a - b - c = -5 - (-2) -6

a - b - c = -5 +2 -6

a - b - c = -5 -6 +2

a - b - c = -11 +2

a - b - c = -9

Les cases de ( a - (b + c) ) :

1) a - (b + c) = 9 - (-1 + 5)

a - (b + c) = 9 - (+4)

a - (b + c) = 9 - 4

a - (b + c) = 5

2) a - (b + c) = 7 - (-6 + (-3))

a - (b + c) = 7 - (-6 -3)

a - (b + c) = 7 - (-9)

a - (b + c) = 7 +9

a - (b + c) = 16

3) a - (b + c) = -3 - (8 + (-4))

a - (b + c) = -3 - (8 -4)

a - (b + c) = -3 - 4

a - (b + c) = -7

4) a - (b + c) = -5 - (-2 +6)

a - (b + c) = -5 - (+4)

a - (b + c) = -5 -4

a - (b + c) = -9
