The general form of an NExS formula is:
where expression defines the calculations needed to generate the cell's value, constraint expression places limits on acceptable values or the circumstances under which the calculation should take place, and comment is any text you want to attach to the cell.
The expression part of NExS formulas looks just like an algebraic formula; it contains values and operators that define the relationships between values.
NExS uses the following conventions for formulas:
0 1 2 3 4 5 6 7 8 9 .
- @ =+
To change a formula in a cell, move the mouse pointer to the cell and choose the Edit Cell operation from the Edit menu or position the cursor in the formula display in the Edit Line.
