# Setting a default horizontal spacing value for math mode [closed]

Is there a way to set a default value for the horizontal spacing in LaTeX math mode? I'm constantly writing

$foo \; bar \; baz$


Where the \; macro sets the space that I am happy with. Is there a command I can add to my preamble so that

$foo bar baz$


displays as if those words were interspersed with \;?

• space is ignored in math mode but if your real constructs are defined with appropriate math classes, then you shouldn't have to add space often. \mathrm{foo} \mathbin{\mathrm{bar}} \mathrm{baz} for example. Perhaps you should provide a complete document showing a real small example – David Carlisle May 12 '14 at 21:20
