189 giste
189× 2=378 rate
(189+378)-168=399 gaini
189+378+399=966 pasari
189*2=378 ( rate sunt la ferma )
189+378=567 ( rate si gaste sunt la ferma )
567-168=399 ( gaini sunt la ferma )
399+189+378=966 ( animale sunt la ferma )
189+ 189*2 + [(189+189*2 ) - 168 ] =
=189+378+[(189+378)-168]=
=189+378+(567-168)=
