To delete a row or column, select a cell and then click Home- - Delete Sheet Rows or Columns. cell Home Insert Insert Sheet Rows/Columns no formatting Delete

Using Functions to Perform Calculations A function performs a that results in a single . A function requires data, called to perform its calculation. The arguments of a function are enclosed in after the function name and are usually cell . The function adds the value of the cells in the range. A is used to separate the first cell reference and the last cell reference in the range. Nonadjacent cells can be used as arguments in a SUM function by separating the arguments with a . value arguments parentheses references SUM colon comma

Functions As a function is typed, a illustrates the structure, or syntax of the function. is the best method for entering a cell range into a function – this helps avoid typing errors. ScreenTip Pointing

Other Functions: The function adds the values of the cells in the range and then divides the result by the number of cells in the range. The function determines the maximum value in the range of cells. The function determines the minimum value in the range of cells. These functions ignore cells that contain or are . AVERAGE MAX MIN text empty

Using Absolute Cell References in Formulas cell references automatically change when copied. A cell reference that does not change when copied is called an cell reference. It contains a sign in front of both the column letter and the row number. To create an absolute cell reference, press the key after entering a cell reference. Relative absolute dollar F4

Inserting a Function into a Formula Instead of typing the name of a function into a formula, click – which places an equal sign in the cell and displays a dialog box for inserting functions into a formula. A range of cells is automatically entered in the Number1 box based on the location of the active cell. You should always this to make sure it is correct, if not make the needed changes. Formulas Insert-Function check

Inserting a Functions Functions can also be inserted by clicking a button in the Function group on the tab. Formulas – can also be used to create a formula with the SUM function. Library Formulas AutoSum

Common Error Values #DIV/0 – The formula is trying to divide by zero #REF – The formula contains a reference that is not valid #NUM – A numeric value is invalid, such as a value that is too large or too small #VALUE – The formula is using the wrong type of argument, such as a label instead of a value. #### - The result of the formula is too wide to fit in the column or the result is a negative time or date value.

Common Error Values A triangle indicates a possible formula error. Common formula errors are: Formula omits adjacent cells. Inconsistent formula in region. green
