SCHOOL OF VEDIC MATHS
Splitting the number 8
(i) 28 x 8 8
8 = 10 - 2 10 - 2
Hence, 28 x 8 = 28 x 10 - 28 x 2
28 x 10 = 280
- 28 x 2 = 56
Answer = 224
Splitting the number 19
(ii) 19 x 32 19
19 = 20 - 1 20 - 1
Hence, 19 x 32 = 32 x 20 - 32 x 1
32 x 20 = 640
- 32 x 1 = 32
Answer = 608
Splitting the number 39
(iii) 42 x 39 39
39 = 40 - 1 40 - 1
Hence, 42 x 39 = 42 x 40 - 42 x 1
42 x 40 = 1680
- 42 x 1 = 42
Answer = 1638
Splitting the number 28
(iv) 28 x 35 28
28 = 30 - 2 30 - 2
Hence, 35 x 28 = 35 x 30 - 35 x 2
35 x 30 = 1050
- 35 x 2 = 70
Answer = 980
Splitting the number 35
(iv) 28 x 35 35
35 = 40 - 5 40 - 5
Hence, 28 x 35 = 28 x 40 - 28 x 5
28 x 40 = 1120
- 28 x 5 = 140
Answer = 980

 43 x 98
 99 x 72
 49 x 64
 38 x 26
 104 x 98

Multiplication 4

  • 1. Multiplication – 4 (from Bhaskara’s Lilavati) Vinay Nair SCHOOL OF VEDIC MATHS
  • 2. Splitting the number 8 (i) 28 x 8 8 8 = 10 - 2 10 - 2 Hence, 28 x 8 = 28 x 10 - 28 x 2 28 x 10 = 280 - 28 x 2 = 56 Answer = 224
  • 3. Splitting the number 19 (ii) 19 x 32 19 19 = 20 - 1 20 - 1 Hence, 19 x 32 = 32 x 20 - 32 x 1 32 x 20 = 640 - 32 x 1 = 32 Answer = 608
  • 4. Splitting the number 39 (iii) 42 x 39 39 39 = 40 - 1 40 - 1 Hence, 42 x 39 = 42 x 40 - 42 x 1 42 x 40 = 1680 - 42 x 1 = 42 Answer = 1638
  • 5. Splitting the number 28 (iv) 28 x 35 28 28 = 30 - 2 30 - 2 Hence, 35 x 28 = 35 x 30 - 35 x 2 35 x 30 = 1050 - 35 x 2 = 70 Answer = 980
  • 6. Splitting the number 35 (iv) 28 x 35 35 35 = 40 - 5 40 - 5 Hence, 28 x 35 = 28 x 40 - 28 x 5 28 x 40 = 1120 - 28 x 5 = 140 Answer = 980
