abstract = {Because we need to know an answer so we can decide what to do. If we’re deciding whether to drive to Virginia Beach for the weekend, we need to estimate how long it will take. If we’re deciding whether to get a solar panel on our new car, we need to estimate how much gas it will save. If we’re deciding between paper and plastic, we need to estimate how much plastic is in the bags we use each year. All these questions (and many more) lead to actions. If the drive is too long, we won’t go to Virginia},
