These discussion problems are designed to make sure
you understand the basic ideas of a numeration system.
Remember, the particular systems are not as important
as the ideas and properties of numeration systems.
See Example 1. Take each symbol separately, find
it's value, and then find the sum of the values of the
given symbols.
See Example 3. Roman numbers include the subtractive
property, so as you read from left to right, add the
value of each numeral unless its value is smaller than
the value of the numberal to its right. Some problems
(such as Problems 24-27) include a bar over some of
the symbols; remember that the bar means multiply the
value of those symbols by 1,000.
See Examples 5 and 6. Don't forget that the
position is important in the Babylonian numeration system.
These are not exactly like any of the examples;
convert all the numbers to decimal form, and then answer
the question.
Look for patterns; Problem 24 is straightforward,
but Problem 25 is tricky.
Look at Example 2; remember that the Egyptian system
is repetitive.
Look at Example 4. Start with the
larger Roman numerals.
Look at Example 7; remember that the Babylonian numeration
system is repetitive.
See Example 2. Treat these problems as puzzles
and have fun with them!
There is no example to match these problems.
Remember the subtractive property when doing these problems.
However, as you go through the book be sure you
look at all the examples in the text. If you need hints
for the Level 3 problems, check some sources for help
on the internet (see the LINKS for that particular section.
As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated "Problem
Solving" generally require techniques that do not have
textbook examples.
There are many sources for homework help on the internet.
