I’ve downloaded the “Math Guide version 4.4” so I could learn how to add columns and rows as in this

Excel example “@sum(B10:B32)”.

Unfortunately, the guide reads like Greek and I can’t read Greek.

Is there a simpler version?

The Math Guide is for the Math Formula editor, which is different from a Calc spreadsheet. The appropriate document is the Calc Guide. See also Getting Started.

However, I looked through these documents, and they do not give a simple answer to your question. Instead of such packaged guides, I normally do a Google search. In this case, the online help is useful.

Here is a simple example.

- In cells A1 and B1, enter
`40`

and`2`

respectively. - Select A1 and B1 and press the
*Sum*toolbar icon. Or, in cell C1, enter`=SUM(A1:B1)`

.

**EDIT**: Updated sum icon link—now allows selection of different functions.

What does the Sum toolbar icon look like?

the Icon for SUM doesn’t exist on my 2 tool bars

It’s part of the main formula bar. Perhaps you unchecked View → Formula Bar.
