Primul mod:
Carnea de vita: 261/3=87
Carne de pui: 261+87=348
Carne de porc ramasa:261-67=194
Carne de vita ramasa:87-67=20
Carne de pui ramasa:348-67=281
In total a ramas: 194+20+281=495 de kg
Exercitiul:(261-67)+[(261/3)-67]+{[261+(261/3)]-67}=194+(87-67)+[(261+87)-67]=194+20+(348-67)=194+20+281=495 de kg
Al doilea mod:
Carne de vita :261/3=87
carne de pui:261+87=348
Total carne adusa:261+87+348=696
S-au consumat: 67*3=201 kg
A ramas:696-201=495 kg
Exercitiul: {261+(261/3)+[261+(261/3)}-(67*3)=[261+87+(261+87)]-201=(261+87+348)-201=696-201=495 kg
