>>11088804>But it reduces the chance of mistakes when you are doing it under pressure, for exaple during exams. I always miss a minus sign, or mess up on simple operations bc of time trouble. Ill look those models up, thanks anonCounterpoint: If your profs give partial credit, a missed sign on hand written work will get you credit, and regardless of how an exam is graded, if a prof can see your process and correct it you'll get more out of the feedback you receive. If you make the same mistake on a calculator, the prof won't know where the issue was and won't be able to correct it. I've had a professor write "I can't tell what you did wrong, and neither can you" on a test question that I tried to punch into a calculator without simplifying.
>>11088816>Scratch that, I guess it's not free anymore. It was just a year or two ago.4 years ago when I was considering buying it it was 150 USD for a student license. According to the website, it's now 165 USD. Well worth it in my opinion, unless you have 24/7 access to a university computer that has it, like I used to have.
