conversations.value: Kelly needs school supplies to teach her class for an art project. She has 8 students and they will need 3 pieces of construction paper each. In addition to the construction paper, she needs to buy 6 bottles of glue for everyone to share. After Kelly purchases these supplies, she dropped half of them down a storm drain. Class is about to start, but she manages to rush to the store and buy 5 more pieces of construction paper. How many supplies are left?

conversations.value: Kelly needs 8*3=24 pieces of construction paper.
  She buys glue which grows the supplies to 24+6=30.
  Unfortunately, she dropped 30/2=15 supplies.
  Rushing to the store, she buys more construction paper bringing her supplies back to 15+5=20.
