NumberMate for Windows

NumberMate is an arithmetic and scientific calculator, adding machine, and time calculator that records your calculations on multiple tapes you can edit. It also does expression evaluation and unit conversion directly on a tape. Use it to make simple, everyday calculations; organize and work simultaneously with several separate but related calculations; make complex sets of interrelated calculations; verify, revise, and reuse calculations; document calculations for future reference; and communicate them to other people. Type directly onto a tape. Edit tapes by typing over the contents. Change, insert, delete, annotate, and sort entries. Cut, copy, and paste tape lines, tape sections, or entire tapes. Exchange columns of numbers with other programs via the clipboard. Embed calculations within calculations. Store calculation results in a table. Show a running total, group totals, grand totals, and item counts. Print and save tapes. Use up to 20 tapes per file to organize calculations.
