  In a store, an Uno Giant Family Card costs $12. When Ivan bought ten pieces, he was given a discount of $2 each. How much did Ivan pay in all?

conversations.value: Instead of $12 each, an Uno Giant Family Card costs $12 - $2 = $10 each.
  Ivan paid $10 x 10 = $100 for the ten pieces Uno Giant Family Card.
