Question

Ex 13. Punctele, g, h, i si j. Multumesc mult

Answer 1

g) -5[-4+(-4)*(-3)-4*2]+4*(-1)=
=-5(-4+12-8)+(-4)=
=-5(8-8)-4=
=-5*0-4=
=0-4=
=-4

h) {46-[13+(18-12):(8-5)]*3}*5=
=[46-(13+6:3)*3]*5=
=[46-(13+2)*3]*5=
=(46-15*3)*5=
=(46-45)*5=
=1*5=
=5

i) {[4500:(-100)-90:2-(-90)]:1999}:25=
=[(-45-45+90):1999]:25=
=[(-90+90):1999]:25=
=(0:1999):25=
=0:25=
=0

j) (-1800+1250):10-220:11-(1200:40-600:15+25)=
=-550:10-20-(30-40+25)=
=-55-20-(-10+25)=
=-75-(+15)=
=-75-15=
=-90
