I have been looking for a latex feature which can show operations in a columnwise fashion. For example:-
If I would want to show $19 * 5$ to a $1$st grader, I would love to show it like this :-
Now obviously this isn't latexed and it looks ugly like this. I have searched for this feature in MathJax basic tutorial and quick reference, but I couldn't find it.
So is there a way to express this multiplication, or any operation in a column wise way?
I would appreciate if someone could tell me a way which also takes letters instead of numbers. I would be able to use them in cryptarithmetic puzzles.
