I am working on an excel spreadsheet that shows data from my students in the
fall, winter, and spring...then a column to show the growth. In the growth
column I want to show the growth from fall to spring. I know I can use
=sum(d3-b3) to get that number. I am wondering if there is a formula to be
able to fill in one formula for 30 rows, so I don't have to type in the above
formula for all 30 rows???
