Is there a command that compresses equation horizontally, so that everything is closer together in the horizontal direction?

This is not for a real document but rather just for viewing and playing around.

Not clear what do you want. Consider adding an MWE, at least specify \documentclass. – pushpen.paul Jun 10 '14 at 13:39
\small ?........ – David Carlisle Jun 10 '14 at 13:44
Do you want, e.g., no (or at least less than normal amounts of) space around +, -, and = symbols? – Mico Jun 10 '14 at 13:44
@DavidCarlisle - Wouldn't \small reduce things vertically as well as horizontally? – Mico Jun 10 '14 at 13:45
You could use the graphics package to rescale it. – John Kormylo Jun 10 '14 at 13:46

enter image description here


\noindent X\dotfill X\[
a+b^{x+y} + \sum_{i=0}^n(x+y)^i + \sqrt{x+y+z} =  2 < a\frac{1+2}{3}b

That's awesome, I'll try it. Thanks. – Faq Jun 10 '14 at 14:08
It's strange that some things (eg things in double-fractions "\frac{\frac{1}{2}}{3}") don't get affected that much by changing the parameters \medmuskip etc. Any reason for this or how one could fix that? – Faq Jun 10 '14 at 14:21
What I'm saying is that if one have an expression of the form \frac{A\times\frac{B}{C}}{D\times\frac{E}{F}} and then one plays around with the parameters \medmuskip etc and the others...A and D changes but B, C, E and F do not since they occur as "double-fractions". Any idea why and how to fix that? – Faq Jun 10 '14 at 14:39
Doesn't \nulldelimiterspace get around fractions, tho? Also you could squeeze a wee bit more with \scriptspace. – morbusg Jun 10 '14 at 14:39
@morbusg yes thanks, updated – David Carlisle Jun 10 '14 at 14:52

Probably your equation is a little bit too long. Then you can manually scale it using \scalebox. Certainly, if the scale factor is far from 1, it must look ugly.

\scalebox seems to have some conflict with "aligned" inside "equation". – Faq Jun 10 '14 at 14:26
