The AutoSum button allows you to quickly insert the SUM function.

2. A drop down menu will appear, from which you can select the formula. Functions can also be 'nested'; that is inserted into larger functions by using the appropriate amount of brackets. =AVERAGE(SUM(B2:F2), SUM(B3:F3)) 1.Yet another way to insert a function is to type the equals sign into a cell and begin to type the name of formula.

Worksheet functions are categorized by their functionality. Click a category to browse its functions. Or press Ctrl+F to find a function by typing the first few letters or a descriptive word. To get detailed information about a function, click its name in the first column. Statistical functions: SUM: Adds a range of cells together AVERAGE: Calculates the average of a range of cells COUNT: Counts the number of chosen data in a range of cells MAX: Identifies the largest number in a range of cells MIN: Identifies the smallest number in a range of cells Financial functions: Interest rates Loan payments Depreciation amounts Accessing MS Excel functions

The parts of a function: Each function has a specific order, called syntax, which must be strictly followed for the function to work correctly. Syntax order: 1.All functions begin with the = sign. 2.After the = sign, define the function name (e.g., Sum). 3.Then there will be an argument. An argument is the cell range or cell references that are enclosed by parentheses. If there is more than one argument, separate each by a comma. An example of a function with one argument that adds a range of cells, A3 through A9:

To calculate the sum of a range of data using AutoSum: Select the Formulas tab. Locate the Function Library group. From here, you can access all available functions. Select the cell where you want the function to appear. In this example, select G42. Select the drop-down arrow next to the AutoSum command. Select Sum. A formula will appear in the selected cell, G42. This formula, =SUM(G2:G41), is called a function. The AutoSum command automatically selects the range of cells from G2 to G41, based on where you inserted the function. You can alter the cell range if necessary.
