If you don't believe this, ask a student to evaluate: 1 + 1 / ( 2 + 1 / ( 3 + 1 / ( 4 + 1 / 5 ) ) ) The correct answer is 225/157 or about 1.4331, but they will spend far more time arguing with you that this expression has no meaning before effortlessly dashing off some ridiculously wrong answer which they neither believe nor doubt.” | |

| Jun 3, 2014 at 16:52 | comment | added | JPBurke | @jpmc26 What part of my comment leads you to believe I have misread the question? My comments were intended to draw attention to the assumptions in the question, and therefore are tied directly to assumptions in the question as written. It is worth reflecting on these assumptions. Comment 1 refers to the assumption that the student shouldn't use the calculator in this case. Comment 2 refers to the assumption that foregoing the calculator, as a better strategy, is something the student needs to be taught to believe. The fact is, understanding our assumptions helps make stronger arguments. | |
| Jun 3, 2014 at 16:38 | comment | added | jpmc26 | @JPBurke You're misreading the question. The OP isn't suggesting that one should never use a calculator. They are looking for a way to justify that this material is worth learning instead of simply always using a calculator. | |

| Jun 3, 2014 at 15:43 | comment | added | Patricia Shanahan | I have seen one practical downside to calculator use. I was tutoring pre-calculus students, and they had problems with factorization partly because they did not see numbers as products and sums of other numbers. | |

| Jun 3, 2014 at 11:32 | comment | added | mrr | I forgot to take a calculator to a chemistry test once, and I still got 97/100 because I know how to do long multiplication/division. They aren't useless. | |
| Jun 3, 2014 at 11:29 | comment | added | JPBurke | Also, technically, your goal (for your purposes) is to get them to do the subtraction without the calculator. It is not to teach them that not using the calculator is better. You can learn mathematics without being convinced about which way is better to practice mathematics in classrooms. | |
| Jun 3, 2014 at 11:27 | comment | added | JPBurke | A question shouldn't make unsupported assumptions, should it? Sometimes the problem motivating the question is in the assumptions. "what should be the correct way to teach someone that it's better not to use the calculator?" If it is not obvious, or you have not proven to yourself or anyone else that it is better not to use a calculator (which you essentially assert here), might not that be part of the reason it is difficult to "teach" students to agree with you? | |
