- Section 0:
-
- Practicing Math is a math program that is set up much like a workbook
- that contains practice problems. This program allows you to choose
- which one of the various mathematical concepts that you want to practice
- on. After choosing from the first menu, you will have a choice from a
- second menu. Then 2 of those submenus (BASIC ARITHMETIC AND ELEMENTARY
- MATH) ask you to choose your level of difficulty. Choose "1" for simple
- problems; or "2" for more difficult problems.
-
- For example: Choosing "1" from the ADDITION submenu of BASIC
- ARITHMETIC main menu gives you single digit addition problems
- such as 5 + 5. Choosing "2" for your difficulty level gives
- you multiple digit addition such as 25 + 357.
-
- You are always allowed 3 tries to enter the correct answer. If, after
- the third try, you still have entered the wrong answer, the program
- will give you the correct answer in a box.

- one such as "3 r 2". The program will generate a wrong answer
- response. The user must enter the 3 (as in the above quotation) and
- then press enter. The program will then prompt with "Remainder is:",
- and at that time, the user enters the 2 (as in the above quotation).
- As with the above submenu choices, the user is prompted for his/her
- difficulty level before it begins the problems. Level "1" is single
- digits, and Level "2" is multiple digits (see ADDITION above).
-
- DOLLARS AND CENTS: Choosing "6" means that you have chosen to do the
- money concepts. This activity is meant to help children be able to
- count money correctly. Again, the user is asked to choose his/her
- difficulty level first. Level "1" consists of answering how many of
- the different coins (penny, nickel, dime, quarter) equal 1 dollar.
- Level "2" is adding up the money that is presented. It asks that you
- use different increments of paper money (20 dollar bills, 10 dollar
- bills, and 5 dollar bills), as well as various amounts of coins. At

- by number of years x 2. 3). Sum-Of-The-Years'-Digits Depreciation:
- depreciation fraction = number of years depreciated divided by the
- sum-of-the-years'-digits (sum-of-the-years'-digits = number of years
- multiplied by (number of years + 1) divided by 2). The last step is:
- Annual depreciation = depreciation fraction x (cost - scrap). Unless
- otherwise instructed, round all answers to the nearest 1/100 decimal
- place.
-
- PROFITS AND LOSSES: Choosing "6" means that you have chosen to do
- problems figuring out profits and losses. The first activity is

- Section 11:
-
- Viewing The Achievement File (registered version only):
-
- Achievement file is a text file and can be viewed using any text editor.
- Simply start text editor and open ACHIEVE.TXT to view. Otherwise, the
- program shows you the achievement file at the start so you can work on
- any areas of problems that you have. The program also shows you your
- file right before it exits so you can see any new scores that were added
- during the program's run. This feature (as stated above) is available
- only in the registered version. The shareware version does not write
- any scores to files.
