Introduction to Excel
Spreadsheets are often used to: Perform basic mathematical operations Find values such as profit or loss Find the average, maximum, or minimum
values in a specified range Graph or chart data to assist users in
identifying data trends Sort and filter data to find specific
information
Formulas
Formulas are the real workhorses of an Excel worksheet
If you set up a formula properly, it computes the answer when you enter it into a cell From then on, it keeps itself up to date,
recalculating the results whenever you change any of the values that the formula uses
All formulas begin with the = sign
Formulas
Addition Select the cell you would like this
information to be in. Type =, then select or type the first cell, followed by the + symbol, and then type or select the next cell you want to add. Press Enter i.e. =A2+B2
Formulas
Adding If you are adding consecutive numbers in a
column or row, you can use the SUM formula. Type =SUM, and then the range you would like to add in parenthesis (you can type or select the range with your mouse). i.e. =SUM(C2:C4)
Formulas
Subtraction Select the cell you would like this
information to be in. Type =, then select or type the first cell, followed by the – symbol, and then type or select the next cell. Press Enter i.e. =A2-B2
Formulas
Multiplication Select the cell you would like this
information to be in. Type =, then select or type the first cell, followed by the * symbol, and then type or select the next cell. Press Enter i.e. =A2*B2
Formulas
Division Select the cell you would like this
information to be in. Type =, then select or type the first cell, followed by the / symbol, and then type or select the next cell. Press Enter i.e. =A2/B2
Graphs
Charts and graphs are a great way of representing your data
Excel offers almost every chart type and makes it easier to draw them so that your data can quickly be understood
