Assumptions
- Addition is computed only from the fields you enter on this calculator. [addition-calculator]
- The wired execution function for `addition-calculator` is the source of numerical behavior.
- Real-number arithmetic is used unless addition explicitly needs integers.
Limitations
- Edge cases outside the intended domain of addition may error or look unstable—treat them as out of scope.
- If multiple conventions exist for addition, this calculator uses the convention implemented in its engine path.
- Complex/branch cuts and undefined points are not always interactively annotated for addition.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
