@Jagra Yes, it will semi-automatically. You will have to open an old notebook and in the Menu/Format/StyleSheet change the StyleSheet to Custom

comment Plotting the real positive solution to a parametric equation
@Community I think, this question is off-topic, since it is based on a simple syntax error.

comment Plotting the real positive solution to a parametric equation
The Bill's answer is pedagogic, but I would prefer to give you a direct answer. If you try your code for NSolve with some numeric a value, say, a=1you will see the following: a = 1; NSolve[x^2 - a == 0 && Element[x, Reals] == True && x >= 0, x] yields the following: {{x -> 1.}}. This is what you get under the operator Plot . For this reason Plotreturns and empty thing. One workaround is to use the belisarius construct given above.

comment UPDATED CODE: Need to utilize FindFit with specified x variable values
It is difficult to understand, what do you want to obtain. If you edit your question adding to it the data (or a part of the data) and the fitting function you have in mind, we might help you.

Thank you, Michael, for such detailed answer. It is certainly of a high value.

comment Adjusting size and positioning of math notation in a Mathematica notebook?
@Michael E2 continuation: option with the OptionInspector, but failed. The OptionInspector does not react on my trial to introduce the change, and immideately switches back to the {0.71} that stayed there initially. So, please tell, if you have another experience. Third, I propose that though a good answer has already been done and accepted, you and @Szabolcs give your versions as the answers, rather than comments. It is because the information is very important.

comment Adjusting size and positioning of math notation in a Mathematica notebook?
@Michael E2 Michael, it is extremely interesting. I have, however, two questions and one proposal. First, it would be very instructive to understand, what properties are controlled by which figure here {ScriptSizeMultipliers -> {1., 0.7, 0.7, 1.}} ? I tried to play with it, and only was able to find that the first, 1.controls the site of the secondary fraction and exponent, and the second figure, e.g., 0.7 controls the offset of the denominator of the secondary fraction. So could you give a hint of the role of the others? Second, I tried to fix the ScriptSizeMultipliers

There is a better way: give the cell where you are going to type the style DisplayFormula or DisplayFormulaNumbered. Done. This works especially nice in the JournalArticle StyleSheet.

comment Adjusting size and positioning of math notation in a Mathematica notebook?
Yes, Mike, but I am a bit experienced. I just made few trials and see, for example, that ScriptSizeMultipliers->{1.0} is easy to add as the option to the whole CellBoxData, and it will give rise to the full size of both fractions and exponents, while addition AllowScriptLevelChange->False by OptionsInspector places it as the FractionBoxOptions for the outer FractionBox. It then only gives the full size of fractions, but not of exponents.

comment Adjusting size and positioning of math notation in a Mathematica notebook?
Thank you, it is very interesting. I have, however, two questions. First I formulated to David, the OP. Please have a look, am I wrong? Second, do you think it might be an alternative to make Shift+Ctrl+E and include the option into the cell code?

comment Adjusting size and positioning of math notation in a Mathematica notebook?
I just do not understand what we are speaking about. I tried to reproduce the behavior in Mma 10.0, Win7 within the Default and JournalArticle StyleSheets in the EquationNumbered cells and do not see the font size reduction, at least, by eye. Could you specify, what type of StyleSheet/Cell do you have in mind?

@funnypony, why don't you then place the expression you have in mind?

as an alternative possibility: Times @@ ToExpression /@ (StringReplace[Map[ToString, List @@ eq], Except[Characters["ab"]] -> "1"]) . Try.
