Răspuns:180:9-16+21+144:8+225:3

=20-16+21+144:8+225:3

=4+21+144:8+225:3

=25+144:8+225:3

=169:8+225:3

=21+1+225:3

=22+225:3

247:3

=81 r 1

i)13.432+164x12-1.395:15-1872:18

=163.152-93-104

=163.059-104

=162.955

j)608:2+50:2x3-75x4

=304+25x3-75x4

=987-300

=687

k)1000-342:6x4+28-799

=658:6x4+28-799

=27+10+28-799

=37+28-799

=65-799

=-734 (aicea trebuie sa faci metoda mersului invers)

t)1000-(241x4-64):100

=1000-(964-64):100

=1000-900:100

=100:100

=1
