6 Calculez. A=-8 × (-3)-(-3) × (-9) +9; B = (10-(-8) ×7) × (6 − (− 4) × (−9)) ; ㅎ C=-5x4+ (-55) ÷ (-7x3+10); D=7-7x (-10) + 17 ÷ (-0,1).​

Bonsoir,

A = 8*(-3)-(-3)*(-9)+9

= 24+3*(-9)+9

= 24-27+9

= 6

B = (10-(-8)*7)*(6-(-4)*(-9))

= (10+8*7)*(6+4*(-9))

= (10+56)*(6-36)

= 66*(-30)

= -1980

C = -5*4+(-55)/(-7*3+10)

= -20+(-55)/(-11)

= -20+5

= -15

D = 7-7*(-10)+17/(-0,1)

= 7+70+17/(-0,1)

= 7+70-170

= -93
