## Arithmetic trainer: Negative numbers operations.

Description: Generation of exercises concerning basic arithmetic operations with negative integer numbers. The operations
(addition, subtraction, multiplication and division) may be chosen by the user.

Please, note that the non integer results (of a division) have to be entered as a fraction and that this fraction must be reduced as much as possible.
Thus, if the question is, for example, 25 / (-10), the only answer accepted as correct by the application is -5/2. Also note that if the result is a negative fraction, the minus sign has to be used with the numerator. Thus, in the example
above, the answer 5/-2 will be considered as false!

Use the Start button to begin the test; after filling in the result, push Solve to check your
answer, then Next for the next exercise. Pushing Eval/Reset shows your success percentage and
re-enables the operator selection for a new test.

Free Pascal features: Basic controls: checkboxes, edit fields, (push) buttons.
