Explicație pas cu pas:
a) -5·(-6) + (-20) = 30-20 = 10
b) +99-(-5)·(-19) = 99 - 95 = 4
c) -10·(+12)+(-7)·(-15) = -120+105 = -15
d) -2·(+3)·(-4)-(-4)·(-3)·(-2) = (-6)·(-4)-12·(-2) = 24+24 = 48
e) (-2+3-44)·(7-5+8) = -43·10 = -430
f) -100·[(-4)·(+5)-(-10)·(+2)-(-3)] =
= -100·[-20-(-20) +3] = -100·(-20+20+3) =
= -100·3 = -300
