Hi. I'm Benjamin from Spain

Sorry if I present myself too late.

However. My name is Benjamin, I’m from Spain and I’n 29 years old.

In my country we have an excellent mental calculator called Alberto Coto.

He brings me into mental calculation after assists at an exhibition of his skills.

So I’m grateful to all people here, specially Kinma, for your help.

I really wants to participate in all topics :slight_smile:
