Writing an explanatory paragrah i want to use an approximately equal symbol. How can I do this? The palette has lots of symbols but not what in latex would be done with \approx. 

When I enter x-y Maple echoes x-y. When I enter y-x Maple echoes y-x. When I enter b - a Maple echoes  b-a.  But when I enter a-b Maple echoes -b + a

I fiind this promotion of negatives, which also occurs in more complicated expression, somewhat confusing.

Is there any description of the rules Maple uses and perhaps ways of controlling them?

If I do:

The font that Maple uses for the Tablulate is much larger than the font used to display the Dataframe. How does one choose the font size that Tabluate() uses?

In the second case RegSubs treats the expression m as containing special characters. Can one tell it to treat what it receives as a literal string - perhaps some "escape" function?
