Sagot :
A=5-(3-5*6) = 5- ( 3-30 ) = 5 - (-27) = 5 + 27 = 32
B=33-3/10+7 = 30 / 17
C=7-(-3.5+(5-4*3) = 7 - (- 3,5 + 5 - 12 ) = 7 + 3,5 - 5 +12 = 5,5 + 12 = 17,5
D=-5-2+8*3-(-4) = - 7+ 24 +4 = 21
B=33-3/10+7 = 30 / 17
C=7-(-3.5+(5-4*3) = 7 - (- 3,5 + 5 - 12 ) = 7 + 3,5 - 5 +12 = 5,5 + 12 = 17,5
D=-5-2+8*3-(-4) = - 7+ 24 +4 = 21
a=5-(3-5*6)
a= 5- (3-30)
a= 5-(-27)
a= 5+27 = 32
a=32
B=33-3/10+7
B= 33-0.3+7
B= 39.7
C=7-(-3.5+(5-4*3)
C= 7-(-3.5+(5-12))
C= 7-(-3.5+(-7))
C= 7-(-3.5-7)
C= 7-(-10.5)
C= 7+10.5
C= 17.5
D=-5-2+8*3-(-4)
D=-5-2+24+4
D= 31
