Yeah, that and also a way to make the display of addition etc. more neat. - without doing weird things like adding latex spaces etc..

I don't see how to get around using spacing, but I would do something like:

\(\displaystyle \begin{array}{cc} & 12 \\ + & 13 \\ \hline & 25 \end{array}\)

\(\displaystyle \begin{array}{cc} & 12 \\ \times & 13 \\ \hline & 36 \\ & 12\quad \\ \hline &156\,\,\,\, \end{array}\)

Why are you linking to that thread in this one? The two threads are not related in any way I can see.
I just wanted you to solve it for me. The problem is interesting. Can you solve SAT math problems? Can you help me "master" calculus 1-3? I want to know calculus 1, 2, and 3 like a pro teacher.
