Using ranges
A range is a rectangular block of cells. The reference for a range
consists of the cell references of the top left and bottom right
corners of the block, separated by a colon, e.g. B2:C6. You can
use ranges to define areas of the worksheet for applying
formatting, creating graphs, or include range references in
formulae, e.g. =SUM(B2:C6).
To select a range: highlight all the cells you want to be a
part of your range.
To use a range in a formula: highlight the range to be
inserted while entering the formula. For example, type
“=SUM(” then drag the highlight to cover the appropriate
range, type a “)” and press Enter.
