Multiply by 9
The method works only when multiplied by 9.
Take 2 hands ... everything is left- dozens. All sprava- unit.
Take the example of multiplication: 9H4. Hold the account is the only one finger at a number of multiply 9. In our case- a 4 finger left.
So we consider: we left before 3 paltsa- bent and as it desyatki- it thirty ... And we've got left 6 fingers. And since this other unit that together turns 36.
Everything!
