How do i enter complex fractions into LO calc?

For example algebraic fractions. I need a horizontal line separating numerator and denominator.

Calc is a module for doing math, it’s a kind of advanced calculator. Math is the module where you produce formulas for display.

In Math you get fractions with {1-x} over {1+x}.
In Calc you can write =(A1+1)/(A1-1)

As mentioned before Math is for displaying formulas, but if you really need it in Calc, you can either use two vertical cells and have a line between them ar simply use the symbol “/” combined with “()”.
