What type of document is created to access a computer's ability to perform high-speed math functions?

The correct choice, a spreadsheet, is specifically designed to handle numerical data and perform complex calculations, which includes high-speed math functions. Spreadsheets utilize built-in functions and formulas that allow users to manipulate and analyze quantitative information efficiently. This capability makes them particularly useful in tasks like financial analysis, budgeting, and statistical analysis, where rapid computation and data organization are essential.

In contrast, word processors focus on document creation and editing, such as writing reports or letters; they are not optimized for mathematical calculations. Presentations are meant for creating visual displays of information to support oral presentations, lacking the computational features required for high-speed math tasks. Databases, on the other hand, are designed to store, retrieve, and manage large sets of structured data, but they do not inherently provide the functionality for performing quick mathematical operations as effectively as spreadsheets do.
