-
1. Multiplying by 11:
Add the digits of a two-digit number together and place the sum in the middle.
Example: 32 × 11 = 352 (3 + 2 = 5)
-
2. Squaring Numbers Ending in 5:
Multiply the number (except the 5) by the next higher number and append 25.
Example: 75² = 5625 (7 × 8 = 56, then add 25)
-
3. Subtracting from Powers of 10:
Use "All from 9, and the last from 10" for subtraction from numbers like 1000.
Example: 1000 - 387 = 613
-
4. Multiplying Numbers Near 100:
Subtract the differences from 100, then cross-add the differences and append.
Example: 97 × 96 = 9312
-
5. Cross Multiplication for Two-Digit Numbers:
Multiply two two-digit numbers using vertical and crosswise methods.
Example: 23 × 45 = 1035
-
6. Finding Square Roots:
Approximate the square root by finding the nearest perfect square and adjust.
Example: √9801 = 99
-
7. Dividing by 9:
Sum the digits of the number. If the sum is divisible by 9, so is the number.
Example: 234 ÷ 9 = 26 (2 + 3 + 4 = 9)
-
8. Nikhilam Sutra for Multiplying Numbers Close to Powers of 10:
Subtract the differences from the base (e.g., 100) and combine.
Example: 98 × 97 = 9506
-
9. Doubling and Halving Method for Addition:
Break up numbers for easier addition by halving one and doubling the other.
Example: 125 + 250 → 250 + 125 = 375
-
10. Quick Multiplication by 9:
Multiply by 10 and subtract the original number.
Example: 9 × 34 = 340 - 34 = 306
