Răspuns:

a) [(419+288÷24+1)÷18-10]×2=

=[(419+12+1)÷18-10]×2=

=(432÷18-10)×2=

=(24-10)×2= 14×2= 28

b) 3×[247+2×(1256-1187)]=

=3×(247+2×69)=

=3×(247+138)=

=3×385= 1155

c) (24×25-595)×[3+10×(10001-9992)]=

=(600-595)×(3+10×9)=

=5×3+90=

=15+90=105

d) 493-3×[12+9×(215-198)]=

=493-3×(12+9×17)=

=493-3×(12+153)=

=493-3×165=

=493-495=-2
