Some people can do it, some people can't. It's something you get better with over time.

Some people can do 2digit by 2digit multiplication fast in their head naturally, others take the time and learn it as they go. It's just a talent type thing that can be learned to some extent.

Definetely don't just jump in and do 4 though. If you are winning at 1, then try winning at 1 while browsing the net, or while chatting with friends whatever. Then play 2 tables, then do 2 tables with distractions etc.

As you get used to it it becomes not much of a problem to play 4 tables while chatting on irc. Especially full-ring.
