spacingsubscripts
When I write $\lim_{x \rightarrow p} f(x) = q$, the subscript x \rightarrow p appears to the right of the limit, instead of directly underneath it.
When I try $\displaystyle \lim_{x \rightarrow p} f(x) = q$, the subscript of the limit takes up extra space, making the line taller than usual and creating an awkward extra space underneath everything else…
Is there a way to write limits in-line with the subscript underneath, and everything squished to the normal height of the line its in?
A simple realization is with amsmath and \underset:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
y=\underset{(20)}{35}\cdot x + \underset{(3)}{39}\cdot z + \underset{(11)}{3859}
\]
\end{document}
However, you see that the first pair is perhaps too wide, because the subscript width is taken into consideration. If the subscript is never much wider than the number, you can use also \mathclap from mathtools; with a new command also the syntax is handier.
\documentclass{article}
\usepackage{mathtools}% also loads amsmath
\newcommand{\twonums}[2]{\underset{\mathclap{(#2)}}{#1}}
\begin{document}
\[
y=\twonums{35}{20}\cdot x + \twonums{39}{3}\cdot z + \twonums{3859}{11}
\]
\end{document}
New lines are treated as spaces. So in your code
\newcommand{\lraB}{ % <-- you are putting a space here!
%lots of latex logic
%so this command is on multiple lines
B % <-- you are putting a space here!
}
If you want to avoid spurious spaces you should end the lines with a comment character %:
\newcommand{\lraB}{% <-- HERE
%lots of latex logic
%so this command is on multiple lines
B% <-- HERE
}

One way would be to use
\scaleboxfrom thegraphicxpackage to rescale the version obtained by\displaystyle. Here is a comparison of the usual inline version of\limand the scaled version:
