Content
You can enter simple formulas such as add, divide, multiply, and subtract two or more numeric values. Or use the AutoSum feature to quickly total a series of values without entering them manually in a formula. After you create a formula, you can copy it into adjacent cells — no need to create the same formula over and over again.
How to do Some Simple Calculation On Worksheet
All formula entries begin with an equal sign (=). For simple formulas, simply type the equal sign followed by the numeric values that you want to calculate and the math operators that you want to use — the plus sign (+) to add, the minus sign (-) to subtract, the asterisk (*) to multiply, and the forward-slash (/) to divide. Then, press ENTER, and Excel instantly calculates and displays the result of the formula.
For example, when you type =12.99+16.99 in cell C5 and press ENTER, Excel calculates the result and displays 29.98 in that cell.
The formula that you enter in a cell remains visible in the formula bar, and you can see it whenever that cell is selected.
Important: Although there is a SUM function, there is no SUBTRACT function. Instead, use the minus (-) operator in a formula; for example, =8-3+2-4+12. Or, you can use a minus sign to convert a number to its negative value in the SUM function; for example, the formula =SUM (12, 5,-3,8,-4) uses the SUM function to add 12, 5, subtract 3, add 8, and subtract 4, in that order.
How to Make Use of Auto sum
the easiest way to add a SUM formula to your worksheet is to use AutoSum. Select an empty cell directly above or below the range that you want to sum, and on the Home or Formula tabs of the ribbon, click AutoSum > Sum. AutoSum will automatically sense the range to be summed and build the formula for you. This also works horizontally if you select a cell to the left or right of the range that you need to sum.
Note: AutoSum does not work on non-contiguous ranges.
