Adding to numbers

[Lori]

Hi All,

I know this is probably a very simple function, but I can't for the life of
me make this work!!! I have a column with all different numbers. I need to
add 3 to each number. Ex. 12.46 needs to change to 15.46. This can be done in
the same column or a different column. Doesn't matter. I just need to add 3
to each number in the column. Right now I'm typing them in

Thanks in advance!

Lori
