expanding button

Hi,

I received a excel file, where there is "+" sign on the left. If I click it,
it expands and click it again collapses. What is that for?

Also I see "1", "2" on the top left. If i click "1" all the "+" expand and
if I click "2" all of them collapse.

What is the difference in these two formulas:
=+A32+A31
=A32+A31

See "About using outlines" in XL Help.


The "+" in the first formula is superfluous. It's often used by Lotus
users who have switched to XL.
