a) =15+15:15·(15+225)=15+15:15·240=15+240=255

b) =250+60:(50-30)·50=250+60:20·50=250+150=400

c) =110:10·(110-80)+670=110:10·30+670=330+670=1000

Explicație pas cu pas:

a). 15+15:15x(15+15x15)=

=15+15:15x(15+225)=

=15+15:15x240=

=15+1x240=

=15+240=

=255

b). 250+60:(50-2x15)x50=

=250+60:(50-30)x50=

=250+60:20x50=

=250+3x50=

=250+150=

=400

c). 110:10x(110-20x4)+670=

=110:10x(110-80)+670=

=110:10x30+670=

=11x30+670=

=330+670=

=1000
