conversations.value: Can you break down the solution for me for this math problem: Out of the 500 marbles that Cindy had, she gave her four friends 80 marbles each. What's four times the number of marbles she has remaining?

conversations.value: Cindy gave her four friends 80 marbles each, a total of 4*80 = 320 marbles
  She was left with 500-320 = 180 marbles
  Four times the number of marbles she has remaining is 180*4 = 720
