Every 4-digit number leads here… 🤯👇
Try it yourself right now:
1️⃣ Pick ANY 4-digit number (at least two different digits).
2️⃣ Arrange the digits from largest to smallest.
3️⃣ Reverse them to get smallest to largest.
4️⃣ Subtract the smaller number from the larger one.
5️⃣ Repeat with your new answer!

💬 Comment your starting number and how many steps it took you to reach 6174!
