Atentie la calcule: a) 33124:2+123-[64×11-12+(22:2+48:8)+132:4]= b) [624:2+(13025-1375):5:5]+(5040-1350):3= c) 36:9+3×[50+3×(400:8-98:2)]= d) 5×(333×3+222×2)-[(2430:1-32×14)-(100-37):7:3]=

Answer 1

a) 33124:2+123-[64*11-12+(22:2+48:8)+132:4]=
    16562+123-[704-12+(11+6)+33]=
    16562+123-(692+17+33)=
    16562+123-742=
    16562-619=15943

b) [624:2+(13025-1375):5:5]+(5040-1350):3=
    (312+11650:5:5)+3690:3=
    (312+2330:5)+1230=
    (312+466)+1230=
    778+1230=2008

c) 36:9+3*[50+3*(400:8-98:2)]=
    4+3*[50+3*(50-49)]=
    4+3*(50+3*1)=
    4+3*(50+3)=
    4+3*53=
    4+159=163

d) 5*(333*3+222*2)-[(2430:1-32*14)-(100-37):7:3]=
    5*(999+444)-[(2430-448)-63:7:3]=
    5*1443-(1982-63:7:3)=
    7215-(1982-9:3)=
    7215-(1982-3)=
    7215-1979=5236
