- Submit homework separately from this workbook and staple all pages together. (One staple for the entire submission of all the unit homework)
- Start a new module on the front side of a new page and write the module number on the top center of the page.
- Answers without supporting work will receive no credit.
- Some solutions are given in the solutions manual.
- You may work with classmates but do your own work.
For each two sets noted, indicate whether or not the sets match. If they do, show a matching. If they do not, explain why not.
a. Small Blue A-blocks and Large Red A-Blocks
b. Yellow A-blocks and Circular A-blocks
Describe a matching between the set of counting numbers, {1, 2, 3, ...} and the set of positive multiples of five, {5, 10, 15, ...}.
Show every possible one-to-one correspondence between the Small Blue A-blocks and the Small Red A-blocks. Use abbreviations or pictures to denote the blocks.
Convert each numeral to a Hindu-Arabic Base Ten numeral.
| a. STROKE: | | | | | | | | | | | | | | | | |
| b. Tally: \(\cancel{||||}\cancel{||||}\cancel{||||} |||\) |
| c. Roman: MCMLXII |
| d. Roman: DCCXLIV |
| e. Roman: \(\bar{\bar{\text{IV}}\text{CCX}}\)DLI |
|
f. Egyptian:  |
|
g. Chinese  |
|
h. Mayan  |
| i. \(4032_{\text{seven}}\) |
| j. \(T6W_{\text{thirteen}}\) |
| k. \(1 \ 111 \ 001 \ 011_{\text{two}}\) |
| l. \(507_{\text{nine}}\) |
Convert 342 to a numeral in the numeration system or base specified.
| a. Roman | b. Base Seven | c. Egyptian |
| d. Base Two | e. Chinese |
Convert 838 to:
| a. Base Twelve | b. Base Eight |
| c. Base Five | d. Mayan |
Convert 13,595 to Base Twelve
Convert 120,258 to Mayan
Count from 620 to 630 in Base Five
State the numeral that comes just before:
| a. \(173 \ 425 \ 760_{\text{eleven}}\) | b. \(2 \ 010 \ 212 \ 000_{\text{four}}\) |
State the numeral that comes right after:
| a. \(539100TE_{\text{twelve}}\) | b. \(3 \ 102 \ 313 \ 444_{\text{five}}\) |
Answer true or false. If false, explain why
| a. \(2_{\text{four}} = 2\) | b. \(3_{\text{four}} = 3_{\text{twelve}}\) | c. \(10_{\text{twelve}} = 10_{\text{five}}\) |
Using Base Three blocks, you had 7 flats, 10 longs and 5 units. What number does this represent in
| a. Base Three? | b. Base Ten? |
Write each number shown in expanded notation as a numeral in the base specified.
| a. \(3 \times 7^{8} + 6 \times 7^{5} + 4 \times 7^{4}\) to Base Seven |
| b. \(1 \times 3^{10} + 2 \times 3^{9} + 2 \times 3^{3}\) to Base Three |
Write each number in expanded notation:
| a. \(200 \ 050 \ 030 \ 000_{\text{nine}}\) |
| b. \(1 \ 000 \ 100 \ 001 \ 000_{\text{two}}\) |
Write each numeral in expanded form. Then, convert each numeral to a Base Ten mixed numeral with the fraction simplified.
| a. \(43.3_{\text{nine}}\) | b. \(35.12_{\text{six}}\) |
| c. \(121.21_{\text{three}}\) | d. \(333.333_{\text{five}}\) |
Rewrite from expanded form to a numeral in the appropriate base.
| a. \(3 \times 4^{2} + 2 \times 4^{0} + 3 \times 4^{-1} + 1 \times 4^{-3}\) |
| b. \(5 \times 11^{3} + 10 \times 11^{1} + 8 \times 11^{-1} + 1 \times 11^{-2}\) |
| c. \(1 \times 2^{2} + 1 x\times 2^{0} + 1 \times 2^{-1} + 1 \times 2^{-4}\) |
