Some calculators for students in grade school have a division key (Int+), which determines the whole number quotient and remainder when dividing one whole number by another. Six classes in a middle school will go on a field trip in vans that each hold seven students. To determine the total number of vans needed, the students will use a calculator with a whole number division key Int+) as illustrated in the screens below. a. For each calculator view screen, determine the whole number quotient (first box of the screen) and the remainder (second box of the screen) for the given numbers of students.
