When you’re doing it in your head? are you actually pictureing the abacus? How do you rememeber wehre all the beads are after every single move? especially in the 7 digits… there are like 30 bits and bosb to rememeber? Are there any tips? 999marge September 27, 2010 at 9:48 am I have been teaching myself Anzan but still very slow after a year. Any suggestions? Shortcuts? also teaching my 10 & 6 yo boys.
