How To Play

Math Master is easy to use. To start a new practice session, click one of the four operation icons (Addition, Subtraction, Multiplication, or Division) or use the menu item, File/New Problems. A box will appear, asking for a number. This number will then be used with a random series of numbers in a range. For example, say that the Addition icon is clicked and the number 5 is chosen. The following math sentences will then be used.

0 + 5 =

1 + 5 =

2 + 5 =

3 + 5 =

4 + 5 =

And so on ...

Keep in mind that the sentences are displayed in random order. The answer to a sentence should be typed into the box. Then hit the <Enter> key. A new problem will be displayed and the process is repeated.

This continues until all numbers in the range have been displayed and answered. If every answer given was correct, the score will be tallied and posted to the Hall Of Fame. If there were incorrect answers, these will be re-asked and if still incorrect, the correct answer is given.

The score is based on the complexity of the problems, the number of problems, and the time in which they were completed. 15 sentences of multiplication by 9 finished in 32 seconds will produce a much greater score than 10 sentences of addition by 2 finished in 20 seconds. By the way, the numbers 5 and 10 score less because they are generally easier to work with.

If a printed sheet of problems are needed, two types can be produced.

•	If a fixed number needs to be worked with (say, Addition by 5), then choose the menu item, File/Print Problems. This will print out a full sheet of random series of equations of Addition by 5.

•	If a random list of numbers needs to be worked with, then choose the menu item, File/Print Random Problems. To understand how to use this, see Printing Math Sentences.


Hall Of Fame

The Hall Of Fame is the listing of the Top Ten scores achieved. Use the menu item Options/Reset Hall Of Fame to erase the current high scores.


Printing Math Sentences

Some On-Line instructions are available to the right of the equation. By moving the mouse over an item on this window, instructions will appear in red lettering.

The number range will always be a random number between 0 and the number you type. For example, if you entered 3 in the upper box (black lettering) and 5 in the lower box (blue lettering) and chose Addition as your operation, you could receive the following math sentences:

3 + 2 =

0 + 5 =

3 + 1 =

1 + 4 =

You could not receive:

3 + 6 =

4 + 2 =

The first number has been limited to a range between 0 and 3. The second number between 0 and 5.

For Addition and Multiplication, the black lettered text box will be displayed above the equation.

For Subtraction and Division, it will be displayed below. The reason for this is that for Subtraction, you must place the greatest number the remainder can be in the lower box. For Division, you must place the greatest number the quotient can be in the lower box.

For example, if you placed 4 in the blue-lettered box and 3 in the black-lettered box for Division, you could receive the following list of sentences:

9 ÷ 3 = (3)

4 ÷ 2 = (2)

0 ÷ 1 = (0)

12 ÷ 4 = (3)

You could not receive:

8 ÷ 0 = ( )

16 ÷ 4 = (4)

8 ÷ 3 = (2.67)

The problem with 8 ÷ 0 = ( ) is that no number can be divided by 0, so Math Master wont print this out.

The problem with 16 ÷ 4 = (4) is that the greatest number the black-lettered box was set to was 3, so 4 cannot be a quotient.

The problem with 8 ÷ 3 = (2.67) is that Math Master wont choose a number that is not an integer. It picks integers within the given range of quotients (black-lettered box) and multiplies them against the given range of divisors (blue-lettered box) to arrive at the dividend.


Range

The range is always between 0 and the number given. Math Master starts with a range of 0 to 12. This can be changed by choosing the menu item Options/New Range.
