I want some advice about how to format it better if I have to write a long text below a $\sum$ or a $\prod$ sign. Basically I want to explain the restriction over which the sum or the product is being taken.   For example how can I improve the looks of these equations,  $N_i (\rho) = \sum _ {B \in \rho s.t n_{\delta_j}(B) = 0    \forall j \neq i} n_{\delta_i} (B)$  $\sum _{ \rho s.t N_i(\rho) = a_i and M_i(\rho) = b_i}    \prod _{B \in \rho} \langle \prod_{i=1}^{n} \delta_i ^{n_{\delta_i}(B)}    y_i ^{n_{y_i}(B)} \rangle_c$

I want to include something in my LaTeX article that will make all mathematical formulae appear in black, while all text (including everything inside \text{}s in the middle of mathematical formulae) appear in red.  Ideally I would like this to be something I could include in the preamble or in a .cls file or something like that.  What would be the quickest way to do that?

Say I have a figure with two subfloats inserted using the subfig package.  When I reference them with \ref{myLabel} I get this     Figure 3.5a and 3.5b.     But what I want is this:     Figure 3.5(a) and 3.5(b).   How can I add the parentheses?

I am able to produce a standard length \sim with a tiny S above it, but I would like the \sim tilde to be longer (maybe one and half times as wide as a capital letter).  Any tips on how to change the width/length of \sim?

I know it has been asked and answered before, and I need to put { and } around it, but for some reason this doesn't work:  \draw (0,0) -- ({atan(1)}:{sqrt(2)});   Any idea why?

I have this case formula which I need to make a little more readable by adding a little more space, vertically, between the two cases.  \begin{cases} f = -\frac {w_1*m + w_2*\frac{-d}{d_M} + w_3*\frac{r}{N} + w_4*s}{w_1+w_2+w_3+w_4} &amp;\hbox{when }m \geq t \\ f = -\frac {w_1*m + 5*w_2*\frac{-d}{d_M} + w_3*\frac{r}{N} + w_4*s}{w_1+w_2+w_3+w_4} &amp; \hbox{when } m&lt; t \end{cases}     How to add an extra space in the latex case above?

I would like to have the formula numbers of the cases environment flush right like regular formulas (not at a fixed distant from the cases like it is by default with the default setting numberdistance=2.5\emwidth). How can I do that?  \starttext  \startplaceformula     \startformula         \startcases             \NC x = 1 \NR[+]             \NC y = 1 \NR[+]         \stopcases     \stopformula \stopplaceformula  \stoptext     What I want (but with the left bracket):  \starttext  \startplaceformula     \startformula         \startalignment[n=1]             \NC x = 1 \NR[+]             \NC y = 1 \NR[+]         \stopalignment     \stopformula \stopplaceformula  \stoptext
