pairs, i.e. one left bracket and then one right bracket per level. Deviation from
the parity of the brackets can be seen in the central status display.

Fraction Term
In a fraction term like
and division are of the same priority and thus performed from left to right. Nu‐
merator and denominator must, however, in each case be calculated from the
quotient. Without brackets. i.e. a*b/c*d, the calculation according to the pri‐
ority rules would be ((a*b)/c)*d (wrong!). Apart from the expression
(a*b)/(c*d) exactly converted into the syntax, the following expressions
would lead to the correct result, as well: a*b/(c*d) and a*b/c/d.

Compilation of the implemented functions
A function call always consists of the function name followed by the argument.
In this connection, the argument does not have to be put into brackets, also if
it has a sign unless it is an expression.
You can fall back on the value of mathematical and other constants using their
constant names. The following constants are available:
ab
cd
