  3. 3. Before implementing the process of division, you must be able to use multiplication table up to 9 x 9 and perform subtraction using abacus. Introduction
  4. 4. Division equation 12 ÷ 4 = 3 Dividend Divisor Quotient
  5. 5. Division Using Abacus <ul><li>(A) PLACES OF DIVIDEND </li></ul><ul><li>1. 1D ÷ 1D (e.g 9 ÷ 9) </li></ul><ul><li>Place the dividend on the 2 nd rod from the place value of “ONES” </li></ul><ul><li>2. 2D ÷ 1D (e.g 46 ÷ 2) </li></ul><ul><li>Place the dividend on the 1 st rod from the place value of “ONES” </li></ul>
  6. 6. Division Using Abacus <ul><li>(A) PLACES OF DIVIDEND </li></ul><ul><li>3. 3D ÷ 1D (e.g 833 ÷ 7) </li></ul><ul><li>Place the dividend on the rod of “ONES” </li></ul><ul><li>4. 4D ÷ 1D (e.g 9613 ÷ 8) </li></ul><ul><li>Place the dividend on the rod of “TENS” </li></ul>
  7. 7. (B) Placing of the quotient <ul><ul><li>If the first digit of the dividend is greater or equal to the divisor, skip one rod to the left of the dividend. </li></ul></ul>
  8. 8. (B) Placing of the quotient <ul><ul><li>If the first digit of the dividend is less than the divisor, place the quotient next (to the left) to the dividend. </li></ul></ul>
  9. 9. (C) Minus the Dividend with the Product <ul><ul><ul><ul><li>Quotient x Divisor </li></ul></ul></ul></ul><ul><ul><ul><ul><li>e.g 72 ÷ 8 =9 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Quotient x Divisor </li></ul></ul></ul></ul><ul><ul><ul><ul><li>e.g 9 x 8 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>So, down 72 at the dividend </li></ul></ul></ul></ul>
  10. 10. Let’s try! 6 ÷ 3 = 9 ÷ 9 = 8 ÷ 2 = 8 ÷ 8 = 9 ÷ 3 = 8 ÷ 4 = 7 ÷ 7 = 6 ÷ 6 =
  11. 11. Let’s try! 91 ÷ 7 = 96 ÷ 8 = 78 ÷ 6 = 84 ÷ 7 = 99 ÷ 9 = 96 ÷ 6 = 49 ÷ 7 = 72 ÷ 9 =
  12. 12. Let’s try! 504 ÷ 7 = 972 ÷ 9 = 612 ÷ 9 = 812 ÷ 7 = 648 ÷ 8 = 533 ÷ 7 = 693 ÷ 9 = 432 ÷ 6 =
  13. 13. Let’s try! 2056 ÷ 8 = 5652 ÷ 6 = 2442 ÷ 6 = 9648 ÷ 8 = 1554 ÷ 7 = 8958 ÷ 6 = 7299 ÷ 9 = 6930 ÷ 9 =
  14. 14. Division with Remainder 8 ÷ 6 = 9 ÷ 6 = 9 ÷ 7 = 5 ÷ 3 = 5 ÷ 2 = 6 ÷ 5 = 7 ÷ 5 = 8 ÷ 7 =
  15. 15. Division with Remainder 82 ÷ 7 = 83 ÷ 6 = 79 ÷ 6 = 43 ÷ 7 = 97 ÷ 8 = 95 ÷ 8 = 66 ÷ 9 = 89 ÷ 9 =
  16. 16. Division with Remainder 796 ÷ 6 = 358 ÷ 7= 888 ÷ 7 = 655 ÷ 9 = 968 ÷ 7 = 284 ÷ 6 = 717 ÷ 6 = 899 ÷ 8 =
  17. 17. Division with Remainder 5735 ÷ 8 = 4796 ÷ 9= 5786 ÷ 6 = 6854 ÷ 7 = 6667 ÷ 7 = 8546 ÷ 9 = 4999 ÷ 6 = 6626 ÷ 8 =
  18. 18. MONEY - ADDITION RM 2.80 + 90 sen = RM 25.65 + RM 25.05= RM 14 + RM 11.55= RM 45.30 + RM16.50 = RM20 + RM65 = RM 32.05 + RM 58.75 = RM 27.90 + RM9.30 = RM69.75 + RM18.80 =
  19. 19. MONEY - SUBTRACTION 75 sen – 20 sen = RM 90.15 – RM 38.80 = RM 97.80 – RM 23 = RM 100 – RM 28.25 = RM 48.75 – RM 22.40 = RM 90 – RM 32.80 = RM 62.65 – 75 sen = RM 80.05 – RM 27 =
