What Can Go Into A Cell?What Can Go Into A Cell?
Labels - describe parts of the spreadsheet Numbers - can be used in calculations Formulas - specify calculations to be
performed Functions - built-in operations the
program knows already

Ranges of CellsRanges of Cells
Many spreadsheet operations apply to more than one cell
A rectangular group of cells is called a RANGE– Identified by the two cells at the corners of the
rectangle– Cell references are separated by a colon ( : )– ex. A1:B6, B8:B12, C3:H3

FunctionsFunctions
Perform some calculation on a range of cells
SUM(F4:F10) -- add up all values in one column
AVERAGE(B18:G18) -- find average of a row
others: MIN, MAX, STDDEV, ….

FunctionsFunctions
Two ways to add all values from D10 through D15– hard way: =D10+D11+D12+D13+D14+D15– easy way: =SUM(D10:D15)
What if range changes to D10 through D215?– USE FUNCTIONS WHENEVER YOU CAN!
