			Press +– ⎟x, to enter a mathematical operation.
			Select the operation and press OK to confirm.
			The available choice of mathematical operations
			depends on the defined formula.
			This means that functions such as "( )" or "ln"/"log" etc.
			are only active if a term in parentheses or the calculation
			of a logarithm is mathematically permissible in the
			defined formula (this also applies to the basic
			mathematical operations).
		+– ⎟x	The following mathematical operations are available:
			•	+ (Addition)
			•	– (Subtraction)
			•	⎟ (Division)
			•	x (Multiplication)
			•	^ (Exponent)
			•	Ln (Natural logarithm)
			•	Log (Common logarithm)
			Press >=< to include logic statements/links/conditions in
