Engineering arithmetic scratchpad
Inputs
A retained label for this saved arithmetic context; it is not parsed.
Allowed characters: numbers, parentheses, +, −, *, /, and ^. Variables and functions are intentionally unsupported.
A user-entered context label for the scalar terms. This workspace does not convert or validate it.
A user-entered display label only. This workspace does not check dimensions or convert units.

When
- Scalar arithmetic only
- Fixed documented grammar
- User-declared unit labels
- No symbolic variables
Don’t
- Declared input label: N. This evaluates only the displayed scalar arithmetic grammar. Formula names and unit labels are retained user context, not parsed or validated. It does not support variables, functions, unit conversion, dimension checking, symbolic algebra, code execution, or engineering-model validation.
