Remember three letters: RTQ - read the question! Once you take your time (a minute, without rushing) to really read it (e.g. have you taken note of the words "buildings", "at least", "fewer than"?), you might find you don't need to make any exact calculations.

Hi everyone

I'm a guest and it's great to be here! For an introduction, let me just share a teaser. If you work at it, it will start rewiring your brain. That’s how it works—if you don’t wrestle with a problem, you don’t get the benefit. So, take this one for a walk in your mind and hopefully experience that satisfying “aha!” moment. Let’s begin. 👉 How many fingers do you have on one hand? Easy, right? 👉 Now, count the pairs of different fingers. Take your time. And now, the real challenge: 💡 How many triples of different fingers are there on your hand? But wait! This time, you must answer WITHOUT COUNTING. Feel free to comment :) Good luck!
