This is the introductory section for the Soroban Level 6 (two-digit divisors). These are supplementary problems for division practice, which form the basis for Level 6 practice. These problems were created by analyzing Level 6 division problems and are based on five key points: Point 1: Problems dividing by multiples of ten Point 2: Problems with two-digit divisors Point 3: Cases where the divisor and dividend are the same (1) Point 4: Cases where the divisor and dividend are the same (2) Point 5: Multiplication check (restitution)
