“There’s a dead body inside the hotel room!!! I’m really scared… Please arrive on time.” The police did arrive, but not quite on time. By the time they arrived, people had already gathered outside Hotel Chandani with a stressed look on their faces. The police entered the room and saw a man stained with blood on his head, and on his back — they immediately declared him dead seeing no signs of life whatsoever. “Definitely not a gunshot” - a police officer insisted as if he was a hundred percent sure. Immediately after, another police officer reached the dead body and measured his temperature while the other officers looked around if the murderer left some clue. The police stayed in the hotel for another hour and a half: some closely inspecting the crime scene, some talking to the owner (who found it difficult to even utter a word), and some asking the gathered mass to return to their places. Before leaving the hotel, the same officer who to...

Why is any number over 0 undefined or what we say infinity?

Why is any number over 0 undefined or what we say infinity? We are used to dividing a certain number by another or by the same number since we started learning mathematics. That’s not a big deal. But here’s one big deal that we are always warned about i.e., to divide any number by zero (0). But Why? Because you get infinity when you do so. But how and why we tend to get so when we divide any number by zero? Let’s have a look at it to better understand!!! ▪ Firstly, what’s multiplication? Nothing but repeated addition. Example: 2×3=6 which means we need to add 2 thrice to get 6. ▪ And secondly , what’s division? Nothing but repeated subtraction unless we get zero. Example: 15/5=3 which means subtracting 5 thrice from 15 to get 0. i.e, 15-5-5-5=0 But let’s check in case of 1/0. Accordin...

Why is ‘6174’ so magical?

Why is ‘6174’ so magical? Let's do some magic today. The special number for this is ‘6174’ . Yes, you heard it correctly. You may be asking what makes this number so significant when it appears to be just another number. Let me tell you that this is a magical number since it connects virtually all four-digit numbers. You can easily understand this if you follow the simple steps of subtraction. Let's unravel the mystery: Step 1: Choose any four-digit numbers, using at least two different digits (1111,7777 are not allowed). Numbers having leading digits (like 0321,0045) are also allowed. I take the current year: 2021 Step 2: Arrange the digits in ascending and descending order, which can have leading zeros if necessary. Ascending order: 0122 Descending order: 2210 Step 3: Subtract th...
