This math topic covers basic division problems applying the concept of distributing items into groups without any remainder. Specifically, the problems focus on determining how many cars are necessary if a certain number of riders are split evenly among the cars. The division in question involves two-digit numbers divided by a single-digit number, ensuring there are no remainders. This type of problem helps enhance understanding of equal distribution in practical scenarios, such as evenly allocating a specific number of items (in this case, riders) into groups (cars).
