Invisible times (or space) in math expressions

[jmtrik]

There is a lot of debate about the invisible times in latex. By default maple adds the invisible times character which looks like a space between parts of expressions.

If you run the following code 

$m=maple("
printf(MathML[ExportPresentation](2*x))
");

it will look like this

Notice the space in between the 2 and the x. To get rid of the invisible times use this code

$m=maple("
exprD:=MathML[ExportPresentation](2*x);
printf(StringTools:-SubstituteAll(exprD, `⁢`, ``))
");

Then your expression will look like this
