conversations.value: This math problem has got me stumped: It takes 50 minutes to cut a woman's hair, 15 minutes to cut a man's hair, and 25 minutes to cut a kid's hair.  If Joe cut 3 women's, 2 men's, and 3 children's hair, how much time did he spend cutting hair?
  Can you show me the way?

conversations.value: He spent 3*50=150 minutes cutting women's hair.
  He spent 2*15=30 minutes cutting men's hair.
  He spent 3*25=75 minutes cutting children's hair.
  He spent a total of 150+30+75=255 minutes.
