I want to insert a 3x3 determinant in MS Word but find any option for doing so under equations. I searched the web but could not find any site that deals with this. How do i insert a determinant in MS Word?

    like this: "1"? - That's the determinant of the 3x3 identity matrix, for example. – jvb Jun 9 '17 at 19:11
  • @jvb, no. Not like that. That is the value of the determinant. I want insert a matrix like structure surrounded by two vertical lines, one on either side instead of square brackets. – MrAP Jun 9 '17 at 19:18
  • I see. I've found this one (for 2x2, but with straight lines): Ctrl-F9 (to insert a field), then type Eq \b\bc\|(\a\ar\co2(1; 3; 4; 2)), Alt-F9 to close the field editor (or to re-open for editing). I guess co3 would be for 3x3? – jvb Jun 9 '17 at 19:32
  • @jvb, that is not working. The determinant that command produces has only one row. – MrAP Jun 9 '17 at 19:52
  • please double-check your string, works with co3 and nine values, too – jvb Jun 9 '17 at 19:58

Open a new equation with Alt+=, then type

A=|\matrix(0&0&0@0&0&0@0&0&0) |

and add space at the end.

  • Maybe I should be more precise: first, open a new equation with Alt + = then type A=|\matrix(0&0&0@0&0&0@0&0&0) | and add space at the end. – Constantin Oct 5 '18 at 18:49

It expands like a table in Word.

  1. Insert your 2x2 using the Equation Tools
  2. Right-click on one of the 4 slots
  3. Go to Insert
  4. Click what you would like to add (row, col)

Hope this helps!

The only way I've been able to find is to select Equation from the Insert tab, and select Ink Equation from the pulldown. This will open a new window in which you can use the mouse to "write" the equation, and it will attempt to "read" it and convert it to useful text, which you can then insert into your document.


Adding a field like

Word formula field, edit view

will result in
