english: AB: 25. The way we can square on most calculators -- let me demonstrate with this one -- is by taking the number, such as five, hitting "times" and then "equals," and on most calculators that will give you the square.
non_english: AB: 25. Na väčšine kalkulačiek vieme dávať na druhú tak,... ukážem vám na tejto, že vezmete číslo, ako 5, stlačíte "krát", a potom "rovná sa" a na väčšine kalkulačiek vám to dá druhú mocninu.
