I remember a friend’s post: “Another day without using Pythagoras’ Theorem.” The first thing that came into my mind was that day, she crossed the street in a diagonal to catch the bus, so I tried to remind her that the hypotenuse is less than the sum of its sides. Maybe she made no calculation, but instinctively we apply mathematics almost every day. During a session on the operative systems module, our lecturer mentioned that every task had a consecutive number assigned. Later, with that number, it was sequentially assigned to a particular processor. E.g., the first one goes to the first processor, the second one to the second, and the third to the third one; however, as there were more tasks than processors, if there were only 7 processors, the eighth task had to return to the first processor, the ninth to the second and so on. He asked what processor would be assigned for task 1234 if only seven processors existed. I knew it was a division we had to calculate, but we had to us...
