In this paper, we analyze the concept of spreadsheet computing in computer algebra. Numerical spreadsheet programs have a unique, intuitively clear semantics. But when the variables used in a spreadsheet program are allowed to assume symbolic expressions as values, the meaning of spreadsheet computations is not defined that simply. We consider several alternative models for what spreadsheet computations could mean in the symbolic context. We describe the implementation of spreadsheet features, based on one of these models, in the visual computer algebra environment MathScribe.
