Fedora 30 snd Calc -

[Bob Goodwin]

I need help getting LibreOffice Calc to accept a simple math function, 
=E1+G2-F2 and use it.

Can someone point me to a good instruction for entering it? I simply 
want to add two columns, E and G, and subtract F. I've done this before 
with out a problem, can't seem to make it work in a new install ...
