The advantage and disadvantage calculator?

Answer 1

economically speaking, the advantage of anything is the marginal benefit (that is, how much you will enjoy the activity on a scale from 1-10 or 1-100) divided by the relative cost (lost wages you could have made somewhere else, effects of the activity, how much you have to pay to participate)

if that "number" is greater than the marginal benefit of doing nothing over the relative cost of doing nothing, your activity isn't worth it.

Answer 2

The big disadvantage of a calculator is that it often gives answers in the wrong form. Consider the question x = 5/3. A calculator will give you 1.6666........7. That is the WRONG answer. Both 5 and 3 are integers, so the answer must be an integer as well. Integers are COUNTED quantities. They are exact. 1.666....7 is not exact. The correct answer comes from old fashioned math and is: 1 2/3. Suppose the problem was that three pirate chiefs have captured 5 beautiful women. How many does each get? 1.666...7 doesn't sound good, does it? Actually, each gets one and they trade the other 2 for cannon balls and rum at the next port. Pirates didn't have calculators, and divided up their spoils right every time.

Answer 3

Advantage - quick, easy, accurate.
Disadvantage - becomes a crutch. You can't carry a calculator with you everywhere!
