The Magic 1089 Trick

1. Pick any three-digit number, where the first and last digits are different (e.g., 532).

2. Reverse the digits (e.g., 235).

3. Subtract the smaller number from the larger one:

4. Reverse the result (e.g., 792).

5. Add the reversed number to the original result:

✨ How to Quickly Multiply by 11 ✨

Want to multiply any two-digit number by 11 in seconds? Follow this trick!

Example: 42 × 11

1️⃣ Take the two digits of the number (4 and 2).
2️⃣ Add them together (4 + 2 = 6).
3️⃣ Place the sum between the original digits: 462.

✅ 42 × 11 = 462!

Another example:
35 × 11 → 3 (3+5) 5 → 385

💡 If the sum is 10 or more, carry over the extra digit!

Example: 76 × 11
7 + 6 = 13 → Place 3 in the middle and add 1 to 7:
836 (not 716)
