 Nov15 comment How to compute large modulos with pen and paper? Oh right ! Thanks Nov15 revised How to compute large modulos with pen and paper? edited body Nov15 comment How to compute large modulos with pen and paper? I don't see what number is multiple of 3 in the first case. Nov15 comment How to compute large modulos with pen and paper? I notice the pattern for the first one. But I can't prove why it's accurate to predict so. Nov14 asked How to compute large modulos with pen and paper?

Seems like the previous notation wasn't an international standard. But it was $[1234567890]_200$ which is the number in base 200 and hence similar once reduced to the modulo.

Thanks ! That was the simplification I was looking for.

This cleared things up ! May7 comment Proof of a Binomial Identity using a combinatorial argument Alright. Thanks. May7 comment Proof of a Binomial Identity using a combinatorial argument $(k+l) \times (k-l) = k^2 - l^2$ May7 comment Proof of a Binomial Identity using a combinatorial argument I see how you could use this as an algebraic proof but I don't think this can be used to prove it using a combinatorial argument. May7 comment Proof of a Binomial Identity using a combinatorial argument I don't see exactly where this is heading. I can agree on the fact of splitting the initial $2k$ items group into two smaller ones but I don't get were the $k^2$ and $l^2$ are coming from May7 accepted Inductive Proof of a countable set Cartesian product May7 asked Proof of a Binomial Identity using a combinatorial argument
