Calculate Addition of Two or more Numbers in Range in MS Excel

You can calculate the total of the numbers in Range. A range is a sequence of cells in columns or rows in Excel Sheet. If you want to learn more about the range, please read our post on cell range in Excel with operations.

Now, to calculate the sum of two or more numbers arrange in the sequence of range in Excel. Follow the step-by-step guide given below with screenshots.

1. Decide Numbers in range to calculate SUM
First of all, decide on the number which you have to use and calculate the sum. Let’s take two numbers in Excel placed sequentially in column B. The range is from B2 to B3 to use and find the total.

The above image showing the two numbers in the range from B2 to B3.

2. Put =SUM in the Cell Where You Calculate Total
Suppose, you have to find the total in the cell B4. You have to place the code =SUM in the cell B4. This is the starting part of calculating the total of the numbers.

You can check the above image to find how to place the code in the B4 cell.

3. Put start Bracket After SUM Function

5. Put Close Bracket After the Range Name
After you got your range cells in the function, you have to put the close bracket. The close bracket completes the SUM function as given in the syntax above in this post.

The above examples showing the function which contains the cell range. It also contains the start bracket and the close bracket.

6. Press Enter to Get Total
Now, the final step in the calculation of the total is to press the enter button. You will get the final total of the cells contains the numbers.

The final total of the numbers will appear as the image given above.

You can find the total of your numbers placed sequentially in range. Change the numbers in the given example as per your requirement.

What will you do if you have numbers placed in a non-sequential manner? Well, you can use the same SUM function and use the steps given in the below section.

So, let’s start learning the method to find the total for non-sequential range cell in Excel.

Add Numbers Placed in Non-sequential Cells in Excel

To explain how to calculate the total for the numbers placed in a non-sequential manner. Let’s take the example of numbers placed in the Excel sheet as shown in the image below.

There are many numbers in the above image example. Few are arranged in range while few are singly placed in Excel. You have to follow the step-by-step process given below.

1. Place =SUM at the cell where you calculate Total
Choose the cell where you want to calculate the total of all the numbers. After you choose the cell, place the code =SUM in the cell where you have to find the total.

The image given above shows that you are going to calculate the total in the cell B7. The placed code is showing the B7 cell.

2. Put Start Bracket after SUM Function

The above showing that, the sum function requires arguments as numbers. However, the syntax is given in this page showing that you can also place cell names as arguments.

3. Press and Hold keyboard ‘CTRL’ button and select all Cells to contain numbers
After you place the start bracket in the SUM function. You have to press and hold the ‘CTRL’ button of your keyboard. Now, click all the cells contains the number while holding the ‘CTRL’ key. This will select all the cells contains the numbers to calculate the total.

The above image showing the selected cells contains numbers. The numbers are not in any sequence and placed in random cells.

4. Put Close Bracket After Selected Cell Names
The cell names are selected inside the function. You have to now put the close bracket to complete the function.

The close bracket is showing in the above image.

5. Press Enter to Get Total
This is the final step where you have to just press the enter key of the keyboard. The total of the selected numbers starts showing in the cell where you want to calculate the total.

The above image showing 281 as the total of numbers using the SUM Function In Excel.

You can as many numbers in the random cells of Excel as you want. After that, you can find the total of all the numbers using the SUM Function In Excel.
