Document Summary
The result is the negative of the input data. These two values are candidates to be in the same equivalence class: on the other hand, -36 and +37 would react differently. In one case, the absolute value is the negative of the input, while in the other case, the output is the same as the input. These two values should definitely be in different equivalence classes: example set of classes, need to look at rules to know how many characters together are valid or invalid (ex. Area code such as 613 and 800 are 3 characters that are either valid or invalid: more precise your categories, more systematic you can be in your testing. 6:
