Answer 1

Răspuns:

Ca sa ne fie mai ușor asociem convenabil termenii

67+256+133+144=256+144 + 133+67=400+200=600(Adevarat)

327+149+73=327+73+149=400+149=549(Fals)

792+29+471+108=792+108+29+471=900+500=1400(Adevarat)

1326+159+423=1485+423=1908(Fals)

1168+4332+3504=5500+3504=9004(Adevarat)

219+341+1235=560+1235=1795(Fals)
