How to use Excel as your calculator
Instead of using a calculator, use Microsoft Excel to do the math!
You can enter simple formulas to 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.

More about simple formulas
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.
Use AutoSum
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.

AutoSum vertically

AutoSum horizontally

In the figure above, the AutoSum feature is seen to automatically detect cells B2:B5 as the range to sum. All you need to do is press ENTER to confirm it. If you need to add/exclude more cells, you can hold the Shift Key + the arrow key of your choice until your selection matches what you want. Then press Enter to complete the task.
Intellisense function guide: the SUM(number1,[number2], …) floating tag beneath the function is its Intellisense guide. If you click the SUM or function name, it will change o a blue hyperlink to the Help topic for that function. If you click the individual function elements, their representative pieces in the formula will be highlighted. In this case, only B2:B5 would be highlighted, since there is only one number reference in this formula. The Intellisense tag will appear for any function.
What can I use in a formula to mimic calculator keys?
Calculator key | Excel method | Description, example | Result |
+ (Plus key) | + (plus) | Use in a formula to add numbers. Example: =4+6+2 | 12 |
– (Minus key) | – (minus) | Use in a formula to subtract numbers or to signify a negative number.Example: =18-12Example: =24*-5 (24 times negative 5) | 6-120 |
x (Multiply key) | * (asterisk; also called “star”) | Use in a formula to multiply numbers. Example: =8*3 | 24 |
÷ (Divide key) | / (forward slash) | Use in a formula to divide one number by another. Example: =45/5 | 9 |
% (Percent key) | % (percent) | Use in a formula with * to multiply by a percent. Example: =15%*20 | 3 |
√ (square root) | SQRT (function) | Use the SQRT function in a formula to find the square root of a number. Example: =SQRT(64) | 8 |
1/x (reciprocal) | =1/n | Use =1/n in a formula, where n is the number you want to divide 1 by.Example: =1/8 | 0.125 |
How to Fill data automatically in worksheet cells
- Select one or more cells you want to use as a basis for filling additional cells. For a series like 1, 2, 3, 4, 5…, type 1 and 2 in the first two cells. For the series 2, 4, 6, 8…, type 2 and 4. For the series 2, 2, 2, 2…, type 2 in first cell only.
- Drag the fill handle .
- If needed, click Auto Fill Options and choose the option you want.
How to create a drop-down list
Create a drop-down list You can help people work more efficiently in worksheets by using drop-down lists in cells. Drop-downs allow people to pick an item from a list that you create.
- In a new worksheet, type the entries you want to appear in your drop-down list. Ideally, you’ll have your list items in an Excel table. If you don’t, then you can quickly convert your list to a table by selecting any cell in the range, and pressing Ctrl+T.
Notes:
- Why should you put your data in a table? When your data is in a table, then as you add or remove items from the list, any drop-downs you based on that table will automatically update. You don’t need to do anything else.
- Now is a good time to Sort data in a range or table in your drop-down list.
- Select the cell in the worksheet where you want the drop-down list.
- Go to the Data tab on the Ribbon, then Data Validation. Note: If you can’t click Data Validation, the worksheet might be protected or shared. Unlock specific areas of a protected workbook or stop sharing the worksheet, and then try step 3 again.
- On the Settings tab, in the Allow box, click List.
- Click in the Source box, then select your list range. We put ours on a sheet called Cities, in range A2:A9. Note that we left out the header row, because we don’t want that to be a selection option:
- If it’s OK for people to leave the cell empty, check the Ignore blank box.
- Check the In-cell dropdown box.
- Click the Input Message tab.
- If you want a message to pop up when the cell is clicked, check the Show input message when cell is selected box, and type a title and message in the boxes (up to 225 characters). If you don’t want a message to show up, clear the check box.
- If you want a message to pop up when the cell is clicked, check the Show input message when cell is selected box, and type a title and message in the boxes (up to 225 characters). If you don’t want a message to show up, clear the check box.
- Click the Error Alert tab.
- If you want a message to pop up when someone enters something that’s not in your list, check the Show error alert after invalid data is entered box, pick an option from the Style box, and type a title and message. If you don’t want a message to show up, clear the check box.
- If you want a message to pop up when someone enters something that’s not in your list, check the Show error alert after invalid data is entered box, pick an option from the Style box, and type a title and message. If you don’t want a message to show up, clear the check box.
- Not sure which option to pick in the Style box?
- To show a message that doesn’t stop people from entering data that isn’t in the drop-down list, click Information or Warning. Information will show a message with this icon and Warning will show a message with this icon .
- To stop people from entering data that isn’t in the drop-down list, click Stop.
- To show a message that doesn’t stop people from entering data that isn’t in the drop-down list, click Information or Warning. Information will show a message with this icon and Warning will show a message with this icon .
