Hello everyone,

My son is high-functioning autistic/Asperger's. He is quite intelligent but has an extreme dysgraphia problem right now that has become apparent since I started homeschooling him. The worst subject matter for him is mathematics since it apparent that he doesn't know his math facts (which I can teach him) but the dysgraphia is even worse since it takes him an extreme amount of time for him to complete any problem (this is a problem of his obsession with perfection combined a lack of fine motor skills).

I'm looking for a good solution for him for writing out his math problems (pre-algebra) and I'm hitting a bit of a wall. One solution would be LaTex and that would probably work with everything from algebra and up but it seems a bit difficult to work with multiplication and division problems where he needs to do carry numbers.

1. Is LaTex a good solution for him to enter long multplication? If not what would be better? I suppose one could try to create a long multiplication spreadsheet template, too.

2. If LaTex is a good solution, could you give me an example of using LaTex for long multiplication? How do you show work, carry forwards, etc. For example how would I show a short multiplication solution of

$\displaystyle 423 \times 211$ . I've attached a long multiplication solution from another website as a graphic file but I'm wondering how I would enter it in LaTex.

Thanks
