Abstract
Systems and methods for computer-based numerical calculation using a calcsheet are provided. A calcsheet may provide one or more columns for vertical calculation, each column having a plurality of fields including operation fields, number fields, and optional comment fields. The calcsheet may include multiple columns of vertical calculations. A user may type in calculations in a manner similar to the entry of calculations on a hand held calculator, and the calculations may be displayed in a vertical format in substantially any column. Number fields in a calcsheet may include mathematical formulas or references to other fields. A set of fields (such as all operation fields in a column, for example) may be hidden. The display order of fields may be altered. Parentheses spanning multiple rows may be used to alter the order of operations. Spreadsheet lines and vertical calculations may be used in a single document or display screen. Mathematical formulas may include a subtotal function which calculates a subtotal of the numeric values from preceding number fields.
