Are you struggling to retrieve the last few digits of a large number in Excel? You’re likely in need of the least-significant digits function. Here, we’ll explain how to use it efficiently to solve numerical problems.

### Overview of the LEFT and RIGHT Functions

**LEFT** and **RIGHT** are two of the most used text functions in Excel. They let you take out a set number of characters from the start or end of a cell.

These functions can be useful when dealing with a lot of data. They make it simple and fast to pick out specific pieces of information.

The **LEFT** function gets the set number of characters from the beginning of the string. The **RIGHT** function does the same for the end. The syntax for both functions is simple: you specify the cell with the text, followed by a comma and how many characters to extract.

Say you have customer names in the format “*Last Name, First Name*“. You could use the **RIGHT** function to take out just the first name. You’d pick the characters after the comma. Similarly, you would use the **LEFT** function to take out the last name, by selecting the characters before the comma.

By knowing these two functions, you can save time and energy when working with large datasets. You can also join them with other functions to make even more powerful tools for data analysis and management.

If you haven’t acquainted yourself with these functions yet, now is the time to do so. With all the data available nowadays, people who don’t know how to work well in Excel risk being left behind in the business world.

Now that you know the introduction, let’s take a closer look at these functions and how to use them in practical scenarios.

### Syntax of the LEFT and RIGHT Functions

To use **LEFT** and **RIGHT** functions in Excel, use the following format: `=LEFT(CELL, NUM)`

or `=RIGHT(CELL, NUM)`

. Replace *“CELL”* with the cell address that contains the text you want to manipulate. Replace *“NUM”* with the number of characters you want returned. Hit enter when you are done.

Remember that text strings should always be enclosed within quotation marks (*” “*). If no value for *“NUM”* is given, all characters will be returned.

These functions can save time by quickly processing large amounts of data. Practicing their use can also help you understand how similar functions, such as **MID**, work.

To get started, practice manipulating numerals in other programs. Examples of Returning Least-Significant Digits in Excel will provide further examples on how this can be implemented.

### Extracting the First Digit from a Number

**Text:**

Enter the number you want to extract the first digit from into a cell.

In an adjacent cell, use the LEFT function with the syntax: =LEFT(cell with number, 1).

Press Enter and you should see the first digit of your original number appear.

For negative numbers, use ABS and MID to extract their first digits.

You can use conditional formatting to highlight cells with first digits matching criteria or ranges.

This method can be used for other positions within a number, changing the value in LEFT.

**Understanding how to Extract the First Digit from a Number is important.**

It helps to identify characteristics within data sets.

By using this tool, you can spot patterns and trends that may have been hidden.

For example: Analyzing sales data for multiple products?

Extract digits from each sale figure and categorize by product type.

This makes it easier to identify key trends and make decisions.

These functions let you analyze data sets of any size or complexity.

### Extracting the Last Digit from a Number

To extract the last digit from a number in Excel, follow these six quick steps!

- Enter the number into a cell.
- Then, use the MOD function:
`=MOD(A1,10)`

where A1 is the cell containing your number. This will calculate the remainder when dividing the number by 10, giving you the last digit. - Press Enter to see the result.
- You may want to format this cell as a number to avoid any mistakes.
- To extract the last digit from multiple numbers, copy and paste the formula into other cells.

This technique can be incredibly useful for analyzing sales figures, calculating percentages, or identifying patterns in numerical sequences. With this technique, and other Excel functions and formulas, you can become an analytical superstar!

Stay tuned for further information on **Extracting a Range of Digits from a Number** – another great tool of data analysis in Excel that can help get insights and understanding around complex cases like conditional formatting, geographical map-style data visualization, or prediction models cleanup routines.

### Extracting a Range of Digits from a Number

Extracting digits from a number in Excel can be an important task. Want to get the last two digits of a year or a sequence within a longer number? Here’s a **5-step guide**:

- Pick the right function: Excel has several options for this, like
**LEFT**,**RIGHT**and**MID**. Which one is best depends on where the range of digits you need is. - Enter your formula: Put it in a cell next to the number you want to extract from. For example, if your original number is in cell A1 and you’re using LEFT to get the first 3 digits, your formula might look like this:
*=LEFT(A1,3)*. - Adjust your arguments: Your 1st argument should point to the cell with the original number (e.g., A1). The 2nd argument will depend on how many digits you need.
- Check your answer: Compare it to your original number to make sure it’s correct.
- Copy and paste: If you need to apply this to multiple cells in a row or column, copy and paste the formula into each one.

It’s also good to practice using these functions with different sample numbers and ranges. And if you’re new to Excel, consider taking a tutorial or course. Finally, troubleshooting errors with **LEFT** and **RIGHT** functions is up next!

## Troubleshooting Errors with the LEFT and RIGHT Functions

Ever struggled with least-significant digits in Excel? You’re not alone! Let’s explore **LEFT and RIGHT** formula functions. They are key for extracting specific digits from cells. But, using them isn’t easy. Errors can happen if the argument isn’t correctly formatted. What if it’s not a number? Or if it’s negative? Or more than the number of digits? We’ll find out. By the end, you’ll understand their usage better.

### Error when the Argument is Not a Number

When the **LEFT** and **RIGHT** functions are used wrongly, an error may happen if the argument is not a number. This refers to when the function is given an argument which cannot be converted into a number.

To fix this issue, follow these 3 steps in Excel:

- Check arguments: Check that all arguments for the function are valid numeric values or cell references containing numeric values.
- Check formatting: Make sure that text values given as arguments don’t have special characters or formatting like commas or dollar signs.
- Use
**ISNUMBER**function: Try using the ISNUMBER function to see if a value is a valid number before passing it as an argument.

If you face this error while using Excel, it is crucial to study the input data and make all needed changes before continuing with calculations.

My colleague experienced this error while using the **RIGHT** function on a cell reference with text instead of numeric value. She identified and corrected her mistake easily by examining each of her inputs and checking their format.

Next, let’s discuss another usual error associated with using these functions: **“Error when the Argument is Negative”.**

### Error when the Argument is Negative

When using the **Left and Right functions** in Excel, an error may occur if the argument is negative. This error message indicates that the value of the argument is higher than permitted or outside the accepted range. To fix this, follow these steps:

*Make sure the input parameter does not contain negative numbers.**Check that you entered a positive number for the ‘number of characters’ argument in the formula.**Use a cell reference instead of a static value for the argument.**Ensure you close the parentheses at the end of the function syntax properly.*

Using the Left and Right functions with large datasets or complex calculations can cause this error. It is important to locate and fix the issue quickly. It may be indicative of other problems with the data.

One example is **Sarah** who received the error – “The first argument must be more than zero.” She found out some cells had negative values, so she removed them and her formula worked.

Another error associated with these functions is “Error when Argument is Greater than Number of Digits,” which occurs when the specified character(s) are more than what is in the cells.

### Error when the Argument is Greater than the Number of Digits in the Number

When the argument is bigger than the digits in the number, Excel shows an error message #VALUE!. This happens when using **LEFT or RIGHT** functions for the least-significant numbers.

To fix this error:

- Check cell references in the function.
- Confirm character count matches the cell.
- No leading or trailing spaces in the cell.
- Formula to calculate character count, e.g. =LEN(A2)

This error appears because Excel can’t find enough digits. For instance, if trying to return 4 characters from a 3-digit number, #VALUE! will show up.

Therefore, double-check inputs and character counts when using these functions. By following troubleshooting steps, users can fix this issue.

**Did you know? Microsoft Excel was first launched for Mac in 1985 and for Windows in 1987.**

Using both **LEFT** and **RIGHT** Functions together, users can extract specific sections of text from a longer string by specifying which side and how many characters to keep.

## Using the LEFT and RIGHT Functions in Combination

Excel—we’ve all heard of it and many of us have used it! It’s perfect for students, businesspeople, or anyone who likes organizing data. But did you know about its functions? Let’s explore one: returning least-significant digits. We’ll use the **LEFT and RIGHT functions together** to get the first and last few digits of a number. Plus, we’ll look at how to extract digits in the middle of the number. Follow me and unlock Excel’s awesome power!

### Extracting the Last Few Digits from a Number

**Extracting the Last Few Digits from a Number:**

Open your Excel sheet and enter the number you want to extract the last few digits from.

In a new cell, type “=RIGHT(A1,X)”. A1 is the cell containing your number and X is the number of digits you want to extract.

Then press Enter and the result will appear in the new cell.

To extract just one least-significant digit, change “X” to 1.

This method avoids manual extraction errors and saves time when dealing with large data sets.

If **LEFT and RIGHT** functions are too tricky, keep practicing until it’s more familiar.

Lastly, use “0” instead of “1” when starting from right or left.

Now, onto **‘Extracting the First Few Digits from a Number’**.

### Extracting the First Few Digits from a Number

Open an Excel worksheet and input the number you want to extract digits from. In the next cell over, use the formula “=*LEFT*([cell containing number], [number of digits])”.

For example, if your original number is in cell A1 and you want to extract the first three digits, you can write “=*LEFT*(A1,3)” in cell B1. Hit Enter and the result will be displayed in the second cell.

If you want the least-significant digits, replace “*LEFT*” with “*RIGHT*” in your formula. *LEFT* and *RIGHT* take arguments in two ways – a reference to another cell or a numerical value.

Using this method saves you from rewriting numbers or counting many times! If you drop off cells slightly to the left of their intended location, *LEFT* or *RIGHT* will fix it.

You can modify your *LEFT* or *RIGHT* formula to extract more than one digit.

Another useful feature of Excel is extracting digits from the middle of a number. This eliminates manual calculations!

### Extracting Digits from the Middle of a Number

Want to extract digits from the middle of a number? Excel’s **LEFT** and **RIGHT** functions make it easy! Here’s a 4-step guide:

- Find the start & end position of the digits you need.
- Use
**RIGHT**to get all numbers right of the start. - Use
**LEFT**to get all but last digits. - Combine these two functions, either by addition or side-by-side.

In simpler terms, identify the digits you need. Then, use **RIGHT** & **LEFT** so only required numbers are displayed. Finally, combine the formulas by adding or keeping them together.

This technique is great for large datasets, saving time & giving accurate results.

Fun fact: Excel was created by Microsoft co-founder **Bill Gates** in 1985. It is now one of the most popular spreadsheet tools worldwide!
