Multiply by 11 Instantly
Add adjacent digits and place the sum in the middle
Steps
- 1Take any 2-digit number, e.g., 36
- 2Add the digits: 3 + 6 = 9
- 3Place 9 between 3 and 6: 396
- 4If sum > 9, carry over
Example
36 × 11 = 396 | 85 × 11 = 935
Subtract from 1000
Use the 9-complement trick: All from 9, last from 10
Steps
- 1Subtract each digit from 9, except the last
- 2Subtract the last digit from 10
- 3Example: 1000 - 648
- 49-6=3, 9-4=5, 10-8=2 → 352
Example
1000 - 648 = 352
Double and Halve

- 2Double 16 → 32
- 37 × 32 = 224
- 4Keep going until numbers are easy
Example
14 × 16 = 7 × 32 = 224
