Calculer:(Détailler les étapes) :
A=15-8+10-11-4,5+3,7+8
B= -12-(-4)+7-(12-3)
C=3-6-(-4+5)+(-19+4)
On donne : a=-10 b=3,5 c= -4
Calculer:
D= -a-b+2-(c-7)+(-1-a)
E=10+a-[a-(b-c+1)]
A=15-8+10-11-4,5+3,7+8
B= -12-(-4)+7-(12-3)
C=3-6-(-4+5)+(-19+4)
On donne : a=-10 b=3,5 c= -4
Calculer:
D= -a-b+2-(c-7)+(-1-a)
E=10+a-[a-(b-c+1)]

1. Réponse nonotata
A=15-8+10-11-4,5+3,7+8
a = 15 +10 +3.7 +8 -8-11-4.5
a = 36.7 -23.5
a = 13.2
B= -12-(-4)+7-(12-3)
b = -12 +4 +7 -(9)
b = -12 +4+7+9
b = -12 +20
b = 8
C=3-6-(-4+5)+(-19+4)
c = 3 -6 -(+1) +(-5)
c = 3-6-1-5
c = 3 -12
c = -9
On donne : a=-10 b=3,5 c= -4
Calculer:
D= -a-b+2-(c-7)+(-1-a)
d = -(-10) -3.5 -(-4-7) +(-1 -(-10) )
d = +10 -3.5 -(-11) +(-1+10)
d = 10 -3.5 +11 +9
d = 10+11+9 -3.5
d = 30-3.5
d = 26.5
E=10+a-[a-(b-c+1)]
e = 10 -10 - ( -10 -(3.5 -(-4) +1 )
e = 0 -(-10 -(3.5+4+1)
e = -(-10 -8.5)
e = -(-18.5=
e = 18.5
