comment Align and sub-indexes.
Oh, the link is interesting.

comment Align and sub-indexes.
I intended to mean by robust something that is not a tweak like this. But seen this solution made me think that there is no way for latex to know the extra space is coming from a sub-index or not. I should have though the question better.

@percusse As usual, you don't know what you are saying.

comment Command for the table Ruffini-Horner algorithm
Can I be picky? It gets an error for constant polynomials.

The package itself gives error 'no room for new \dimen .' even for the examples in the package manual.

comment Pgf plot square not positive
That was the problem. Maybe some changes from MikTex 2.8 to 2.9 made that happen. Before I was not having that problem. I tried the brackets but forgot about the braces thing. Thanks.

I should read the things I write.

comment Numbers outside Math environment
Yes, counters on their own have nothing to do but I was asking when LaTeX automatically uses them for numbering pages or sections. How does it treat them? For example if it uses the counters as text I don't want to be putting all numbers in math mode because then a number I am using for counting may look different from those numbering the sections or the pages.

Thank you. I know there is a way but always forget how is it.

How is it you find the page where the Underfull warning came from?

comment A letter in the same space as another
Very good. Question: Shouldn't the command be used as \mathmakeboxlargestof{y}{\alert{z}}{y} and \mathmakeboxlargestof{y}{\alert{z}}{\alert{z}} respectively? Just in case the alert is making some space.

comment Package for changing font with each letter?
For effect, in a poster. Not for a whole long text, that's for sure. It would be painful to read a whole page written like that.

comment \frac{1-z^{n+1}}{1-z} doesn't look very good and how to leave space equal to the size of a given text
Very good answer. One question, why is it that you have to apply phantom to the whole thing and then have to overlap instead of phantom only the exponent?

comment \frac{1-z^{n+1}}{1-z} doesn't look very good and how to leave space equal to the size of a given text
@Caramir: As I said, typesetting is content dependent. The goal is to convey meaning without distraction. \frac{1}{1-z} is just perfect. But the nature of what we are writing now is different from the formula for the geometric progression.

comment \frac{1-z^{n+1}}{1-z} doesn't look very good and how to leave space equal to the size of a given text
Oh my! Now I understand. I never put in the question that what I'm writing is many sums of geometric progressions. My bad.

comment \frac{1-z^{n+1}}{1-z} doesn't look very good and how to leave space equal to the size of a given text
There is still one more reason for wanting that alignment and it is the mnemonic device we use to remember the formula for the sum of a geometric progression. It is easy to remember because we only need to write the same thing 1 minus the ratio and an exponent above that is the number of terms. Visually this picture is broken if the two things are not aligned. The centering doesn't aid the understanding of the formula. Very true that, in general, one would like fractions to be centered but typesetting is content dependent.

I don't think that that is true. It is difficult to parse centering a large expression. Clearly one can write the numerator draw a line below it and center 1-z in the denominator. Think about what would happen if instead of z you had a mammoth expression as the ration of the geometric progression.

comment \frac{1-z^{n+1}}{1-z} doesn't look very good and how to leave space equal to the size of a given text
It is more general for hiding a text, but my main interest is solving the problem with the fraction. Are there cases in which the \hfill doesn't behave well for. I mean, is there some problem if I change z and n by something else?

No. It is a vestigial error from a previous attempt that I forgot to delete. Anyways, it is not a good solution even without it. See the one by Philipp
