OmniDocHow to set Word formula number with chapter number (such as 1-1)
Explain the method of formula numbering with chapter number (such as 1-1) in Word: use the multi-level list of title 1 to get the chapter number, use the SEQ field to make the formula numbering start from 1 again in each chapter, and give the steps and verification methods.
Key points of this article
- The chapter number must be generated by a multi-level list in the "Title 1" style. This style must be applied to the text section titles, otherwise the field cannot get the chapter number.
- The number is composed of two fields: STYLEREF takes the chapter number, SEQ Equation \s 1 takes the serial number in this chapter, and adds a dash in the middle to get 1-1.
- The \s 1 switch of the SEQ field will re-count at each first-level heading, so the formula for Chapter 2 will start at 2-1 instead of continuing from the previous chapter.
- After inserting, press Ctrl+A to select all and then press F9 to update the field, and use Alt+F9 to view the field code to quickly locate numbering errors.
- The format of formulas and numbers can be fixed with tab stops or a frameless three-column table to prevent numbers from being misaligned in the formula row.
When many people write papers or technical reports, the formulas need to be arranged according to "chapter number-serial number". For example, the formulas in the first chapter are (1-1), (1-2), and the formulas in the second chapter start from (2-1). If you just manually type the formula into "(1-1)", once the chapters are adjusted, the numbers have to be changed one by one, and it is easy to miss. This kind of requirement is very common in papers, textbooks and technical manuals. Readers who search for "word formula followed by number 1-1" and "word formula automatic numbering (1-1)" mostly want the number to change automatically with the chapter.
This article only talks about formula numbers with chapter numbers, that is, the first half of the number changes with the chapter, and the second half is re-counted within each chapter. It is different from the ordinary "(1), (2), (3)" consecutive numbers, and the setting ideas are also different. After reading this, you'll be able to create 1-1 style numbers that automatically update in Word, and know where to check when something goes wrong.
How to create formula numbers with chapter numbers? One sentence conclusion
Use the multi-level list of "Title 1" to generate the chapter number, and then use two fields to spell out the number: the former field takes the chapter number, and the latter field takes the serial number within the chapter, with a dash in the middle. In this way, the numbering can be automatically generated, and it can also start from 1 again in each chapter.
| your situation | Recommended practices | reason |
|---|---|---|
| There are only a few formulas in the whole text, and there are no plans to adjust the chapters. | Manually enter the number, such as "(1-1)" | Simple operation, no domain involved |
| There are many formulas, chapters may be added, deleted or rearranged | Title 1 Multi-level list + STYLEREF + SEQ \\s 1 | Chapter numbers and serial numbers will be updated automatically |
| The text should quote a formula number | Bookmark numbers and use cross-references | The quoted text will change along with the number |
| The formula should be centered and the number should be on the right | Tab stop or frameless three-column table | The layout is stable and line breaks are not messy |
| Papers have school or journal format requirements | The numbering format specified in the template shall prevail. | The format is inconsistent and the automatic numbering needs to be changed as well. |
Before you start: Confirm these points first
Whether the chapter titles should uniformly use the "Title 1" style. The field needs to take the chapter number from the title. Only paragraphs with "Title 1" applied will be recognized. If some chapter titles are just ordinary text in bold, the chapter number will not be included in the numbering. Before you start, you can use the navigation pane to check whether each chapter title appears in the first-level table of contents.
The numbering format of multi-level lists must be pure numbers. If the first-level numbering is set to "Chapter 1", the chapter number field will bring "Chapter 1" into the numbering as a whole, and the result becomes "Chapter 1-1". It is recommended to choose a numbering format that only contains numbers. If you need the text "which chapter", please put it in the chapter title itself.
Which insertion method is used for the formula. A common practice is to insert formulas into paragraphs and then use tab stops to push the numbers to the right. The other is a three-column frameless table with formulas in the middle and numbers on the right. The table is more stable, and the numbers are not easily crowded when formulas are wrapped. The tab stops are more compact, which is suitable for short formulas.
Whether the number should be enclosed in parentheses and what symbols should be used to connect it. Parentheses are commonly used in Chinese papers, and the connector can be a dash "-" or other symbols required by the journal. Set the domain after confirmation to avoid later rework.
Determine the language version first. The title style name of the Chinese version of Word is "Heading 1" and the English version is "Heading 1". The style name in the field code must be consistent with the local machine, otherwise an error message will appear.
Steps to set 1-1 formula numbering in Word
- Apply title 1 to the chapter title and set up a multi-level list. Open the multi-level list in "Home", link the first-level list to "Title 1", and set the numbering format to pure numbers (such as "1"). After that, "Title 1" will be applied to each chapter title, and the chapter number will be automatically generated.
- Insert the formula and format it. Insert formulas into the text. If you use tab stops, set a center tab stop and a right tab stop in the paragraph: enter a tab character, put the formula, enter another tab character, and leave room for numbering. If you use a table, create a table with 1 row and 3 columns without borders, with formulas in the middle column and numbers in the right column.
- Insert a left bracket in the number position, and then insert the chapter number field. Enter "(" to the right of the formula, then press Ctrl+F9 to insert the field's curly braces, enter
STYLEREF "标题 1" \sin the curly braces, and press F9 to update. It will display the chapter number of the current chapter. - Enter a dash and then insert the serial number field. Enter "-", then press Ctrl+F9 to insert a new field, enter
SEQ Equation \* ARABIC \s 1, and press F9 to update. This field displays the serial number within the chapter, recounted at each first-level heading. - Add the right bracket and check the display effect. Enter ")", and the number should be displayed as "1-1". If this result is not displayed, do not continue to insert the following formulas and go to the third part to check.
- Copy the numbering structure to subsequent formulas. The new formula can copy the already numbered paragraph or table row, and then modify the formula content. After copying, select the numbered part and press F9 to update and confirm that the numbers are correct.
- When you need to cite, bookmark the number. Select the entire number (including brackets and two fields), add a bookmark, and give the bookmark an easily identifiable name. When the text needs to be quoted, use the cross-reference function, select bookmarks for the citation type, and select bookmark text for the citation content. When the number changes, the reference will be updated accordingly.
- Update the domain once for the full text. Press Ctrl+A to select all, then F9 to update all fields. The domain shortcut keys in the Mac version are different from those in Windows. You can find the function of inserting a domain in the menu to complete the same operation.
Check each item after completion
| Check items | How to see | What to do if there is a problem |
|---|---|---|
| Whether the chapter number is displayed | Check whether the first half of the number is the number of the current chapter | Check if the chapter title applies "Title 1" and update the fields |
| Is there any extra text in the numbering format? | Look for "Chapter 1-1" or "1.-1" | Change the first-level format of the multi-level list to pure numbers, then select all and press F9 |
| Does the new chapter start from chapter 1? | Check the number of the first formula in each chapter | Make sure the SEQ domain contains \s 1, select all, and press F9 |
| Check if the "Error" message appears | Check if the numbering shows "Error!" Or bookmarks are not defined | Press Alt+F9 to check the domain code and verify that the stylename matches the local machine |
| Check if the numbering position is misaligned | Print preview to see if the numbers are aligned to the right | Adjust tab position or switch to a frameless table |
| Whether the references are synchronized | After revising the chapter order, check the main text for citing text | Update all domains; If still incorrect, check whether the bookmark contains the full number |
One thing to note: the field shows the results of the last update. After modifying a chapter or formula, if there is no update, the numbers you see may be old. Before printing or submitting, it is recommended to select all and update once.
📊 Core Comparison
| Method | Operating volume | After chapter adjustments | Suitable for the scene |
|---|---|---|---|
| Manually enter "(1-1)" | Low | Each one needs to be modified one by one | There are few formulas, and the structure remains basically unchanged |
| Title notes + manually stitch chapter numbers | Middle | Serial numbers are automatic; chapter numbers need to be manually changed | Chapters are fixed, just want to count automatically |
| Header 1 Multilevel List + STYLEREF + SEQ \s 1 | Medium and high school | Chapter and serial numbers are automatically updated | There are many formulas, chapters will be adjusted, and the main text needs to be quoted |
The first two methods are easier to set up initially, but you have to change the chapter number whenever it changes; The third setup involves more steps, but it brings long-term stability. If your document is frequently modified, it is recommended to start with the third method.
🎯 Which method suits you?
- Write short reports or assignments with only three or five formulas: manually enter the number, no need to set up fields for it.
- Writing a graduation thesis or manuscript involves dozens of formulas, chapters will be adjusted: Set the heading 1 multi-level list and two fields according to the method in this article, with stable results.
- Frequently quoting formulas in the main text: Be sure to bookmark and use cross-reference; do not directly type "equation (2-3)" in the main text.
- Documents must be submitted to journals or schools: First, review the numbering styles specified in the template, such as bracket types, connectors, and alignment methods, then decide on how to set them.
❓ Frequently Asked Questions (FAQ)
1. The serial number displays "Error!" Or "Wrong!" "Undefined bookmarks"—what is the reason?
In most cases, the style name in the domain code does not match the native Word; for example, the Chinese version says "Heading 1". Change the style name in the domain code to the corresponding "Heading 1" or "Heading 1" for the local machine, then select all and press F9. If the citation is incorrect, check whether the cross-referenced bookmark has been deleted.
2. Can the "Title Notes" function be used to directly insert the 1-1 code number?
By default, the caption only generates consecutive serial numbers and cannot directly obtain a combination of chapter number plus serial number. The practical approach is to insert the tag "Formula" in the title caption, add the \s 1 switch in the domain code, and then concatenate it with the chapter domain. Title notes are suitable for managing numbering and cross-references, while the chapter number part still needs to be obtained using the STYLEREF field.
3. Why does the formula in Chapter 2 not start from 2-1, but instead follows the numbering from the previous chapter?
Usually, the SEQ domain lacks the \s 1 switch, or the section title does not use the "Title 1" style. After adding the switch or correcting the style, select all and press F9 to update. The number will be recounted by chapter.
4. After copying the formula number to another document, why did it become ordinary text or the number was lost?
Domains may be converted to plain text when copy-pasted, or the target document may not have the same heading style and multi-level list. If automatic numbering is required, operations should be done within the same document, or the entire document should be copied instead of individual paragraphs.
5. Should the numbering be set in a separate font?
It is recommended to use the same font as the numbering and formula, and keep it consistent with other numbering. Set the font on the paragraph where the number is located or on the table cell. Do not change just one field in the number, to avoid inconsistent formatting after the update.
📝 Summary
For formula numbering with chapter numbers, the core is to use a "Title 1" multi-level list to obtain the chapter number, then use the \s 1 switch in the SEQ field to restart each chapter with the sequence number. After setting the steps, just press F9 to update the field, and the 1-1 format will automatically change with the chapter.
