The Problem - Learning Math

The problem is to help 4th graders in the Durham community learn their multiplication and division facts. There are software tools that generate sheets of random problems but they could generate problems more than once or give too many easy problems such as multiplying by 0 or 1.

Your task is to generate a random math sheet of multiplication and division problems such that there are not too many easy problems, all the hard problems are there, and each problem only appears on the sheet once. We want to make sure that they get to practice most of their facts! Here is the description of what should be on the math sheet.

• The sheet should have 100 multiplication and division facts on it using single digits from 0-9 for multiplication facts and using the same problems for division. Such as 8*9= and 72/8=.
• It will probably work best to print the problems 5 per line with a blank between two rows and two blanks between each group of 10 problems. an extra blank
• The output should be generated randomly, so each time the student takes a 100 fact test, the problems are different and in a different order.
• Make sure all the hard problems (those multiplication problems with only digits from 6-9 or corresponding division problems such as 6*7= and 49/7= ) appear at least once. We want to make sure they always practice the harder problems like 7*8=
• Make sure each problem appears at most once. Note that 5*8= is different than 8*5=, so at least one of these should appear and both could appear, but there should not be two occurrances of 8*5=
• Those problems with digits 1 or 0 should be used with low priority so there are not too many easy problems. At least one problem with each digit (0-9) should appear.
• Notice that there is no input for this program. The output should be to a text file OR can be to the console. The output should have all 100 problems fit on a standard sheet of 8 1/2 x 11 paper. See the sample output file. Note the output should be different each time you run the program.

Design/Style

• Think about which classes and methods you will need to write.
• Think about what data should be state data
• Include appropriate comments: one for each method and a comment for complicated sections of code inside a method. Include comments for state data.
• Use meaningful variable names.
• Include a paragraph description or outline of your design in your README file.

• Add an informational comment to your main class such as below. // Author: Prof. Rodger // // Date: April 23, 2010 // // Purpose: ????? //

Submit

• In the same project, create one text file called README that includes the following information.
  1. Include a paragraph description or outline of your design in your README file.
  2. Your name
  3. The date
  4. An estimate of how long it took you to do this assignment.
  5. The names of anyone you spoke with about this program. If you discussed the solution with another student, include their name. If you received help from a UTA or the professor, include their name.

Once your program is ready to submit. You need to submit it under assign10mathSheet
