Whole Numbers & Numeration Mayan Numbering System: (AD 300 - 900) Abacus: (500 BC - Present) Basics - Calculations are performed by placing the abacus flat on a table or one's lap and manipulating the beads with the fingers of one hand. Each bead in the upper deck has a value of five; each bead in the lower deck has a value of one. Beads are considered counted, when moved towards the beam that separates the two decks. The rightmost column is the ones column; the next adjacent to the left is the tens column; the next adjacent to the left is the hundreds column, and so on. After 5 beads are counted in the lower deck, the result is "carried" to the upper deck; after both beads in the upper deck are counted, the result (10) is then carried to the leftmost adjacent column. Floating point calculations are performed by designating a space between 2 columns as the decimal-point and all the rows to the right of that space represent fractional portions while all the rows to the left represent whole number digits file:///C|/HP/Math/Math_Teachers/Resource/suppl...ntary/4_numbering_systems/numbering_systems.htm (3 of 4) [06/05/2001 11:07:56 AM] 2.2.

Note the pattern if zeros To convert a decimal that begins with a non-repeating part, such as 0.21456456456456456..., to a fraction, write it as the sum of the non-repeating part and the repeating part. 0.21 + 0.00456456456456456... Next, convert each of these decimals to fractions. The first decimal has a divisor of power ten. The second decimal (which repeats) is convirted according to the pattern given above. file:///C|/HP/Math/Math_Teachers/Resource/suppli...ntary/Appendix_B_Fraction_Decimal/appendix_B.htm (1 of 2) [05/25/2001 12:01:36 PM] Appendix B - Fraction to Decimal Comparison Table preceed the repeating decimal: 0.022222222... = 2/90 21/100 + 456/99900 Now add these fraction by expressing both with a common divisor 0.00054545454... = 54/99000 0.00298298298... = 298/99900 Adding zero's to the denominator adds zero's before the repeating decimal. file:///C|/HP/Math/Math_Teachers/Resource/suppli...ntary/Appendix_B_Fraction_Decimal/appendix_B.htm (2 of 2) [05/25/2001 12:01:36 PM] Appendix C - First 200 prime numbers Appendix C - First 200 prime numbers 2 73 181 613 743 1231 1399 xxxx 2063 2221 3 79 191 617 751 1237 1409 1531 2069 2237 5 83 193 619 757 1249 1423 1543 2081 2243 7 89 197 631 761 1259 1427 1549 2083 2251 11 97 199 641 769 1277 1429 1553 2087 2267 13 101 211 643 773 1279 1433 1559 2089 2269 17 103 223 647 787 1283 1439 1567 2099 2281 19 107 227 653 797 1289 1447 1571 2111 2287 23 109 229 659 809 1291 1451 1579 2113 2293 29 113 547 661 811 1297 1453 1583 2129 2297 31 127 557 673 821 1301 1459 1993 2131 2309 37 131 563 677 823 1303 1471 1997 2137 2311 41 137 569 683 827 1307 1481 1999 2141 2333 43 139 571 691 829 1319 1483 2003 2143 2339 53 151 587 709 853 1327 1489 2017 2161 2347 59 157 593 719 857 1361 1493 2027 2179 2351 61 163 599 727 859 1367 1499 2029 2203 2357 67 167 601 733 863 1373 1511 2039 2207 2749 71 173 607 739 1229 1381 1523 2053 2213 2753 179 file:///C|/HP/Math/Math_Teachers/Resource/supplimentary/Appendix_C_prime_numbers/appendix_C.htm [05/25/2001 12:02:44 PM] Appendix D: Pascal's Triangle to Row 19 Appendix D: Pascal's Triangle to Row 19 1 1 1 1 1 1 1 1 1 1 1 1 13 1 15 1 1 1 1 105 455 560 136 153 171 680 816 969 364 3060 1365 1820 2380 330 715 1001 3003 4368 5005 28 330 6435 1 9 45 165 55 11 13 1 91 14 455 15 560 16 680 3060 3876 11628 27132 50388 75582 92378 92378 75582 50388 27132 11628 1 120 2380 8568 1 105 1820 6188 8568 18564 31824 43758 48620 43758 31824 18564 1 78 364 1365 4368 6188 12376 19448 24310 24310 19448 12376 1 12 286 1001 3003 1 66 715 8008 1 10 220 2002 5005 8008 11440 12870 11440 8 495 1287 3003 1 36 120 792 1716 1 7 84 462 6435 6 210 924 3432 1 21 56 252 1716 3003 15 126 462 1 5 35 70 792 1287 2002 10 126 210 1 4 20 56 495 286 91 120 17 18 19 16 165 3 35 84 120 220 78 14 45 66 15 28 1 6 10 21 36 55 12 1 1 10 11 1 6 8 9 3 4 5 7 1 2 136 816 3876 1 17 153 969 1 18 171 file:///C|/HP/Math/Math_Teachers/Resource/supplimentary/Appendix_D_pascal_triangle/appendix_D_2.htm [05/25/2001 12:04:19 PM] 1 19 1 Appendix E.

Fifth and sixth are supposed to be just that: fifth and sixth. But, with the seventh, another fork has been taken. The General Conference of Weights and Measures (CGMP, from the French; they have been headquartered, since 1874, in Sevres on the outskirts of Paris) has now decided to name the prefixes, starting with the seventh, with the letters of the Latin alphabet, but starting from the end. Now, that makes it all clear! Remember, both according to CGMP and SI, the prefixes refer to powers of 10. Mega is 106 , exactly 1,000,000, kilo is exactly 1000, not 1024. file:///C|/HP/Math/Math_Teachers/Resource/suppl...endix_E_Power_of_10/Appendix_E_power_of_ten.htm (3 of 3) [05/25/2001 12:05:46 PM] Appendix F.
