The nice thing about using a spreadsheet is that you can experiment with numbers without having to RE-DO all of the calculations

LabelsLabels are text entries –they have no are text entries –they have no numerical value.numerical value.

CONSTANTS CONSTANTS ValuesValues

Constants (values)Constants (values) are used to enter are used to enter FIXED number data.FIXED number data.

A constant can be any kind of specific A constant can be any kind of specific number: currency, percent, decimalnumber: currency, percent, decimal

# Working with Constants## Working with Constants# When you are working with constants or When you are working with constants or

values, you must use the appropriate values, you must use the appropriate symbols.symbols.+ + is the symbol for additionis the symbol for addition-- is the symbol for subtractionis the symbol for subtraction** is the symbol for multiplication is the symbol for multiplication// is the symbol for division is the symbol for division
