NumberMate is an arithmetic and scientific calculator, adding machine, and time calculator that records and files your calculations on multiple tapes which you can edit. It also performs unit conversion and arithmetic expression evaluation directly on a tape. Use it to (1) make simple everyday calculations, (2) manage and work simultaneously with several separate but related calculations, (3) make and record complex sets of interrelated calculations, (4) verify, revise, and reuse your calculations, (5) document your calculations for future reference, and (6) communicate them to other people. Type directly onto a tape. Record calculations the same way you would write them on a sheet of paper. Edit tapes anywhere, anytime by typing over the tape contents. Change, insert, delete, annotate, sort numbers. Cut, copy, paste tape lines, tape sections, entire tapes. Use links (like spreadsheet references) to automatically copy the total from one calculation into one or more other calculations whenever that total changes. Embed calculations within calculations. Store calculation results in a table. Show a running total, group totals, grand totals, item counts. Exchange columns of numbers with other programs via the Clipboard. Print a tape to a printer, an Internet Document (htm) file, or a Microsoft Word Document (doc) file - (requires Word 97, or a later version, installed on your computer). Save tapes to a file. Open and work with more than one file at a time. Use up to 20 tapes per file to manage separate but related calculations.
