Precedence: (), *, /, %, +, -. Decimal: . point
Expression: (1+2.5+3)*5-(7/3) Result: 30.1666...
6 * 9 % 7 Result: 5
6 * (9 % 7) Result: 12
If expression is selected:
clear it with a new entry,
modify it with arrow-left or right.
Use Alt+underlined-key to move in document, and Tab or Shift+Tab for next or previous.
You can use the numeric keyboard, with Shift key for its arrows.
For ºFahrenheit-ºCelcius conversion when you enter any of the two (go with Alt+F or Alt+U)
the other one equivalence is shown.
For measures conversions select the type with Alt+1...6 and open the box with
Alt+Down-arrow. Select the desired conversion with down-arrow or up-arrow and
pulse Alt+o directly, which will make the factor (multiply by) to be copied in the
expression line, for the addition to the right of it of the quantity for which the
equivalence is to be calculated.
