  9. Multiplication Using Fingers

  10. JadualPendarabanbolehdibahagikankepada 3 jenis • Sifirbawahsepuluh (6-10) • Sifirsepuluhkeatas (11-15) • Sifirbawahduapuluh (16-20)

  11. Below Ten Tables (6-10) • Namakanjarikelingkingsebagai 6, jarimanissebagai 7, jaritengahsebagai 8, jaritelunjuksebagai 9 danibujarisebagai 10. • Langkah 1: dekatkankedua-duajari yang diperlukanuntukpendarabannombor. • Langkah 2: Anggapkanjari yang terlibat (sebelahbawah) sebagairumahpuluh. • Langkah 3: Anggapkanhasildarabbilanganjari yang selebihnya (sebalahbawah) sebagairumah unit..

  12. Example 1: For 7 x 8 • Step 1: Join the fingers 7 and 8.  • Step 2: Take the involved 5 fingers as tens. • Step 3: Take the products of the remaining fingers 3 x 2 = 6 as 0. Hence 7 x 8 = 56

  13. Example 2: For 9 x 9 • Step 1: Join the fingers 9 and 9. • Step 2: Take the involved 8 fingers as tens. • Step 3: Take the products of the remaining fingers 1 x 1 =1 as one. Hence 9 x 9 = 81

  14. Above Ten Tables (11-15) • Name the little finger as 11, ring finger as 12, middle finger as 13, forefinger as 14 and thumb as 15 of your two hands. • Step 1: Join the fingers, which the product is required.  • Step 2: Take the product of the involved fingers as ones. • Step 3: Take the sum of the involved fingers as tens. • Step 4: Take always 1 as the hundreds place.

  15. Example 1: For 12 x 13 • Step 1: Join the fingers 12 and 13.  • Step 2: Take the product of the involved fingers 2 x 3 = 6 as ones. • Step 3: Take the sum of the involved fingers 2 + 3 = 5 as tens. • Step 4: Take 1 as hundreds. Hence 12 x 13 = 156

  16. Example 2: For 13 x 13 • Step 1: Join the fingers 13 and 13.  • Step 2: Take the product of the involved fingers 3 x 3 = 9 as ones. • Step 3: Take the sum of the involved fingers 3 + 3 = 6 as tens. Its value is 60. • Step 4: Take 1 as hundred. Its value is 100. Hence 13 x 13 = 100 + 60 + 9 = 169

  17. Below Twenties Tables (16 – 20) • Name the little finger as 16, ring finger as 17, middle finger as 18. fore finger as 19 and thumb as 20 of your two hands. • Step 1: Join the fingers which the product is required. • Step 2: Take the product of the remaining fingers on either side and take it as ones. • Step 3: Take the sum of the involved fingers as twenties. • Step 4: Take 2 as hundreds.

  18. Example 1: For 17 x 18 • Step 1: Join the fingers 17 and 18.  • Step 2: Take the product of the remaining fingers 3 x 2 = 6 as ones. • Step 3: Take the sum of the involved fingers 2 + 3 = 5 as twenties. Its value is 5 x 20 = 100 • Step 4: Take 2 as hundreds. Hence 17 x 18 = 200 + 100 + 6 = 306

  19. Example 2: For 19 x 19 • Step 1: Join the fingers 19 and 19. • Step 2: Take the product of the remaining fingers 1 x 1 = 1 as units. • Step 3: Take the sum of the involved fingers 4 + 4 = 8 as twenties. Its value is 8 x 20 = 160. • Step 4 : Take 2 as hundreds. Hence 19 x 19 = 200 + 160 + 1 = 361

  20. Multiplying By Nine Here is a simple way to multiply by nine using your fingers.

  21. MATHS KNOWLEDGE Hold your fists next door to each other, knuckles upwards. Label the knuckles and gaps between the knuckles with the months.You have a knuckle left over, so ignore it. Now, all the knuckle months have 31 days, and the gaps are either February, or have 30 days.

  22. The End...
