Add: +, Subtract: -, Multiply: *, Divide: /, Remainder: %.
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 �Fahrenheit-�Celcius 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.
------------------------------------------------
Square root: Math.sqrt(x)
Math.sqrt(144) Result:12
Raise x to power y: Math.pow(x,y) 
PI constant: (3.14159...): Math.PI 
(4/3)*Math.PI*Math.pow(radius,3)
	Result: sphere volume, with given radius.
