🔢 1. Multiply Any 2-Digit Number by 11 (In Seconds!)

This is one of the fastest tricks in mental math. Here's how it works:

Trick:
Take any 2-digit number. Add its digits and insert the result in between.

Example:
43 × 11
→ 4 + 3 = 7
→ Answer: 4 7 3 → 473

Another example:
52 × 11 → 5 + 2 = 7 → 572

This trick works perfectly for numbers where the sum of the digits is less than 10.

🟩 2. Square Numbers Ending in 5 (Without Calculator)

Trick:
If a number ends in 5, you can find its square instantly.

How?
Multiply the first digit by the next number, then place 25 at the end.

Example:
25² = 2 × 3 = 6 → Add 25 → 625
65² = 6 × 7 = 42 → Add 25 → 4225

Try it with 85², 95², etc. You’ll be amazed!

🧠 3. Multiply Any Number by 5 Quickly

There’s no need to write the full multiplication process.

Trick:

• If the number is even → divide by 2 and add 0

• If it’s odd → subtract 1, divide by 2, and add 5

Examples:
86 × 5 → 86 ÷ 2 = 43 → Add 0 → 430
37 × 5 → (37 - 1) ÷ 2 = 18 → Add 5 → 185

Easy and fast!

🔍 4. Check if a Number is Divisible by 9 (Without Division!)

Trick:
Add all the digits. If the result is divisible by 9, then the number is divisible by 9.

Example:
729 → 7 + 2 + 9 = 18 → 1 + 8 = 9 → ✅ So, 729 is divisible by 9
1341 → 1 + 3 + 4 + 1 = 9 → ✅ Divisible!

📊 5. Quick Percentage Calculation (In Your Head!)

Want to find 10% or 5% of a number fast?

Trick:

Examples:
10% of 600 = 60
5% of 1000 = 1000 ÷ 20 = 50

Use this in shops, exams, or everyday calculations!
