When a formula is entered correctly and the data used in the formula changes, Excel automatically recalculates and updates the answer.
This tutorial covers in detail how to create and use formulas and includes a step-by-step example of a basic Excel formula. It also includes a complex formula example that relies on Excel's order of operations to calculate the correct answer.
Note The instructions in this article apply to Excel 2019, 2016, 2013 and 2010; Excel Online; Excel 2019 for Mac, Excel 2016 for Mac, and Excel 2011 for Mac.
You should be able to add co.calculate after your loop. You might also just be able to change Application.Calculation = xlAutomatic before your loop, and then change back to Application.Calculation = xlManual after the loop. In this video I use Excel for Mac 2011 Version 14.2.3 I show you how to calculate mean, standard deviation and standard error in Microsoft Excel. Cell values let you to reference an Excel cell, instead of the specific value inside the cell so that the contents of the cell can change without the function that refers to the cell having to change. Enter a formula that refers to values in other cells.
Excel Formula Basics
- Feb 22, 2018 Thanks for taking the time to look! I am running Excel for Mac 2016. One suggestion that has been made on other forums is to momentarily set the calculation mode to automatic, but this is not an option for me, as that will crash the program.
- To change the mode of calculation in Excel, follow these steps: Click the Microsoft Office Button, and then click Excel Options. On the Formulas tab, select the calculation mode that you want to use.
Writing a spreadsheet formula is a little different than writing one in math class.
Always Start With the Equal Sign
The most notable difference is that Excel formulas start with the equal sign instead of ending with it.
Excel formulas look like this:
=3 + 2
instead of:
3 + 2 =
=3 + 2
instead of:
3 + 2 =
The equal sign (=) always goes in the cell where you want the formula's answer to appear. The equal sign indicates that what follows is part of a formula and not just a name or a number.
Once a formula is entered, the cell containing the formula shows the answer, rather than the formula. To see the formula, select the cell that contains the answer and the formula appears in the formula bar located above the worksheet.
While this simple example works, it has one major drawback. If you need to change the data used in the formula, you need to edit or rewrite the formula.
Improve Formulas with Cell References
It's better to write a formula so that the data can be changed without having to change the formula itself. This is done by entering the data in worksheet cells and then selecting the cells that contain the data to be used in the formula.
This way, if the formula's data needs to change, the change is made by altering the data in the worksheet cells, rather than altering the formula itself.

To tell Excel which cells contain the data you want to use, each cell has an address or cell reference.
About Cell References
- A cell is the intersection point between a vertical column and a horizontal row on the worksheet.
- Each column is identified by a letter at the top of the column, such as A, B, and C.
- Each row is identified by a number located at the left edge of the row, such as 1, 2, and 3.
- A cell reference is a combination of the column letter and row number that intersect at a cell's location, such as A1, B2, C3, and W345.
- When writing cell references, the column letter always comes first.
To find a cell reference, look up to see which column the cell is in and then look to the left to find which row it is in.
The current cell (the reference of the selected cell) is also displayed in the Name Box located above column A in the worksheet.
Enter the data into cells C1 and C2 and write this formula instead:
Excel Basic Formula Example
Before you start building formulas, enter all data into the worksheet first. This makes it easy to tell which cell references need to be included in the formula.
Entering data in a worksheet cell is a two-step process:
- Type the data in the cell.
- Press Enter or select another cell to complete the entry.
Tutorial Steps
To enter data as illustrated in the example accompanying this section:
- Select cell C1 to make it the active cell.
- Type a 3 in the cell and press Enter.
- Select cell C2.
- Type a 2 in the cell and press Enter.
Enter the Formula
- Select cell D1, which is the location where the results of the formula will appear.
- Type the following formula into cell D1:
- Press Enter to complete the formula.
- The answer 5 appears in cell D1.
- If you select cell D1 again, the complete formula =C1+C2 appears in the formula bar above the worksheet.
Typing the cell references as part of a formula is a valid way of entering them, as proven by the answer of 5 in cell D1. But, there is another way to do it.
Enter Cell References With Pointing
The best way to enter the cell references in a formula is to use pointing. Pointing involves selecting cells to enter their cell reference in the formula. The main advantage of using pointing is that it helps eliminate possible errors caused by typing in the wrong cell reference.
In this step of the tutorial, you'll select cells to enter the cell references for the formula in cell D2.
- Select cell D2 to make it the active cell.
- Type the equal sign ( = ) in cell D2 to start the formula.
- Select cell C1 to enter the cell reference in the formula.
- Type a plus sign ( + ).
- Select cell C2 to enter the second cell reference into the formula.
- Press Enter to complete the formula.
Update the Formula
To test the value of using cell references in an Excel formula, change the data in cell C1 from 3 to 6 and press Enter.
The answers in both cells D1 and D2 automatically change from 5 to 8, but the formulas in both remain unchanged.
Mathematical Operators and the Order of Operations
Creating formulas in Microsoft Excel is not difficult. It is just a matter of combining, in the right order, the cell references of your data with the correct mathematical operator.
Mathematical Operators
The mathematical operators used in Excel formulas are similar to the ones used in math class. https://frontever348.weebly.com/blog/canon-mg3100-printer-manual-mac.
- Subtraction – minus sign ( - )
- Addition – plus sign ( + )
- Division – forward slash ( / )
- Multiplication – asterisk ( * )
- Exponentiation – caret ( ^ )
Order of Operations
If more than one operator is used in a formula, Excel follows a specific order to perform the mathematical operations.
This order of operations can be changed by adding brackets to the equation. An easy way to remember the order of operations is to use the acronym BEDMAS.
- Brackets
- Exponents
- Division
- Multiplication
- Addition
- Subtraction
How the Order of Operations Works
Any operation(s) contained in brackets is carried out first, followed by any exponents.
After that, Excel considers division or multiplication operations to be of equal importance. These operations are carried out in the order they occur, from left to right in the equation.
The same goes for the next two operations, addition and subtraction. They are considered equal in the order of operations. Whichever one appears first in an equation, either addition or subtraction, is carried out first.

Use Multiple Operators in Excel Formulas
This second formula example requires Excel to use its order of operations to calculate the answer.
Enter the Data
Open a blank worksheet and enter the data shown in cells C1 to C5 in the image above.
A More Complex Excel Formula
Use pointing along with the correct brackets and mathematical operators to enter the following formula into cell D1:
Press Enter when you're finished and the answer -4 appears in cell D1.
Detailed Steps for Entering the Formula
If you need help, use these steps to enter the formula:
- Select cell D1 to make it the active cell.
- Type the equal sign ( = ) into cell D1.
- Type a round open bracket ( ( ) after the equal sign.
- Select cell C2 to enter the cell reference in the formula.
- Type the minus sign ( - ) after C2.
- Select cell C4 to enter this cell reference into the formula.
- Type a round closing bracket ( ) ) after C4.
- Type the multiplication sign ( * ) after the closing round bracket.
- Select cell C1 to enter this cell reference into the formula.
- Type the plus sign ( + ) after C1.
- Select cell C3 to enter this cell reference into the formula.
- Type the division sign ( / ) after C3.
- Select cell C5 to enter this cell reference into the formula.
- Press Enter to complete the formula.
- The answer -4 appears in cell D1.
- If you select cell D1 again, the complete function =(C2-C4)*C1+C3/C5 appears in the formula bar above the worksheet.
How Excel Calculates the Formula Answer
Excel arrives at the answer of -4 for the formula above using the BEDMAS rules to carry out the various mathematical operations in the following order:
- Excel first carries out the subtraction operation (C2-C4) or (5-6), since it is surrounded by brackets and gets the result of -1.
- Excel multiplies the -1 by 7 (the content of cell C1) to get an answer of -7.
- Excel skips ahead to divide 9/3 (the content of cells C3 and C5) because division comes before addition in BEDMAS to get a result of 3.
- The last operation that needs to be carried out is to add -7 + 3 to get an answer for the entire formula of -4.
If you want to add up a column or row of numbers, Excel has a built-in formula called the SUM function that makes the job quick and easy.

I have a large workbook from which I am trying to build reports, including multiple graphs. The workbook has to be in Manual Calculation mode to work. I have compartmentalized the calculations into different sheets, and written vba scripts to run calculations on different combinations of sheets. The problem I am running in to is that after I run these scripts, the graphs that I have will not update. The data does update, and if I manually go in to the graph and 'select data' and re-select the same data then they will update. Is there a way I can automate this at the end of my script? I have tried different suggestions on different forums, but nothing seems to work. Here is the code I am currently working with, but it will not update the graphs:
