conversations.value: I'm completely lost with this math problem: Harrison Elementary School is overcrowded with 1590 students, so 40% of the students are going to move to a new school. There are 3 grade levels, and each grade level needs one 20-person advanced class and the rest of the students divided evenly into 6 additional classes. How many students will there be in each normal class at the new school?
  Can you give me a hand?

conversations.value: First find how many students go to the new school: 1590 students * .4 = 636 students
  Then divide that number by 3 to find how many students are at each grade level: 636 students / 3 grades = 212 students/grade
  Then subtract the 20 students in the gifted class: 212 students - 20 students = 192 students
  Then divide that number by 6 to find the number of students in each other class: 192 students / 6 classes = 32 students/class
