english: What I'll use is the second row this time, and I'll get four of you to each yell out a two-digit number, and if you would square the first number, and if you would square the second, the third and the fourth, I will try and race you to the answer. OK?
non_english: Sada ću koristiti drugi red i vas četvoro - jedan, dva, tri, četiri -- doviknite mi dvocifreni broj, a vi kvadrirajte prvi broj, a vi drugi, pa treći i četvrti, a ja ću se utrkivati sa vama ko će brže do rešenja.
