Doing Math in Different Language

[Julián Miranda (Spain)]

It would be interesting if someone with a mother tonge which is written from right to left like arabic or hebrew could explain how they write a technical paper with formulas. You are writting right to left, switch to left to right for formulas and continue right to left?
For the original post of this thread I agree with Didier or ggauny, we calculate in our mother tongue. I remember when I started studying English, reading simple sentences with numbers in it, like an address, was a problem because I read the numbers in spanish. It took an aditional effort to "translate" numbers, as Didier said, 8 was "ocho" (in Spanish) for me. The additional effort was to convert 8 in eight.
Very interesting also the "feeling" Alberto explains in the previous post.
