I am looking to create a vertical equal sign that might function similarly to an underbrace. I often use this symbol when taking notes on paper.

 (x+z) + (y+d) = 10
  ||      || 
  5       5

The alignment is not entirely perfect in this example but I believe the idea comes across.

    You could also use \underbrace{..}_{{}=5}. – Werner Mar 2 '13 at 9:46
  • @Werner Yes that's functional but I'd personally prefer it with no braces and a rotated equals sign. – jaynp Mar 2 '13 at 9:49

Here is another way of achieving this. You use the command \equalto{equation}{value}.





    \equalto{(x + z)}{5} + \equalto{(y + d)}{5} = 10


And this is the output:

enter image description here

As you can see, I added some spacing to the vertical equal manually (and some horizontal spacing to the \equalto command), of course, you can tweak both to get the exact output you want.


thanks to detexify, I just found that if you are using amsmath,amssymb then you have access to \shortparallel


$$\stackbelow{(x+z)}{5}+\stackbelow{(y+d)}{5} = 10.$$

The result, obtained thanks to quicklatex:
