Addition & Subtraction

[Kera]

Please help! I am very new and want to know how to add and subtract dollar
amounts and distances in a column. Hey, stop laughing (haha), I know this
MUST be simple, but I can't figure it out. I am used to excel testing out
Microsoft Project. Thanks for whatever help anyone can offer!!

Hello Kera,
In any Table, insert a custom field such as "Number1" :
Insert / Column...

Select this column, then
Tools / Customize / Fields...
In the Customize Fields dialog:
Click the Rename button to rename your field as you want
Click the Formula button to write a formula
Select a "Rollup" option to calculate the value at the summary level.

Hope this helps,
