Open Formula resulted from the belief by some users that the syntax and semantics of table formulas were not defined in sufficient detail. Version 1.0 of the specification defined spreadsheet formulae using a set of simple examples which show, for example, how to specify ranges and the SUM() function.
The endpoint adjoining the square bracket is known as closed, while the endpoint adjoining the parenthesis is known as open. If both types of brackets are the same, the entire interval may be referred to as closed or open as appropriate.

LibreOffice Calc is the spreadsheet component of the LibreOffice software package. [5] [6]After forking from OpenOffice.org in 2010, LibreOffice Calc underwent a massive re-work of external reference handling to fix many defects in formula calculations involving external references, and to boost data caching performance, especially when referencing large data ranges.
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
A Control key (marked "Ctrl") on a Windows keyboard next to one style of a Windows key, followed in turn by an Alt key The rarely used ISO keyboard symbol for "Control". In computing, a Control keyCtrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl+C).
Default Emacs keybindings include Ctrl+X Ctrl+S to save a file or Ctrl+X Ctrl+B to view a list of open buffers. Emacs uses the letter C to denote the Ctrl key, the letter S to denote the Shift key, and the letter M to denote the Meta key (commonly mapped to the Alt key on modern keyboards.) Thus, in Emacs parlance, the above shortcuts would be ...
An open formula is a formula that contains at least one free variable. [citation needed] An open formula does not have a truth value assigned to it, in contrast with a closed formula which constitutes a proposition and thus can have a truth value like true or false. An open formula can be transformed into a closed formula by applying a ...
