Expresso's Simple Features & Rules:
➤ all dependent expressions are calculated automatically
➤ press Enter in any place of an expression or just after the last square bracket to calculate a value
➤ use square brackets [ ] for expressions. For example: [2+2].
➤ use variables in your expressions. For example: [10*x].
➤ input the name of a variable before the expression followed by ":". For example: [x:2+2], variable x will have the value 4.
➤ move the cursor or click on an expression to edit
➤ calculations can be saved in RTF format.
You can associate a value with a variable such as [x:10*5] and then use the variable in another expression such as [x/52]. When you calculate the variable "x" all dependent expressions are calculated automatically.
