Do you think is ok that some students fail science and engineering

Yes. Scientists and engineers need to calculate values.

For mathematics, no. You should never be allowed to use a calculator in the first place and if you make a sign error or whatever you go back and fix it.

If you make a king armor under false assumptions that it'll solve the arrow problem when it doesn't, the king will fucking kill you.

"Oh yes, I got it right." No you didn't.

Dead blacksmith.

I'm talking about university math, not your high school problems.

Theres a difference from transcribing a sign wrongly from one line to another and making a division error when simplifying an equation. Especially if your error leads you to a value which is logically incorrect or unit wise incorrect. If you get to a point and dont check if your final equation gives you a reasonable answer, then you done fucked up and deserve the failing grade.

or you know, tldr, Harden the fuck up and stop being a bitch. You fucked up try again next time and then dont fuck up.

I think isn't fair that a guy failed a course because they calculator doesn't support matrix operations and other people pass the course because they can afford a calculator that even makes symbolic algebra.

what university math courses have you taken that allow a calculator?

>>7713098
I am in my second year as a math major and I have never required a calculator for an exam. Math really mostly is not about numbers.

Discuss it with your professor. They might have a spare. Regardless, learn how to do it by hand. Knowing for a semester you are incapable of doing a problem in a test environment and doing nothing about it screams that you have no interest in actually succeeding and just want an easy excuse for your failure.

>find the roots of x^4 + 2x2 - 3000 at hand
>find the matrix inverse of [.017 .2441 .256; .457 .211 .554; .55125] at hand
when you have just an hour for complete the test and these are just some operation you have to do.

lol what class is that

i don't remember a calculator helping for linear algebra and calc 3 we didn't intro to proofs we didn't and odes we probs did for finding homogeneous equation

You motherfucker do you have any idea how long motherfucking long division takes?

You mean a 13 dollar ti83?
Also: you can usually write programs to do these yourself.

Most professors I have come across in my chemical engineering faculty don't penalize to hard for a mistake like droping a - or if you wrote the expression you wanted to solve for correctly on your test but you fuck up entering it in the calculator.

As for university classes not needing calculators, it depends on the class and how the proffer sets up questions. On my last final I did ( process control) i needed to iterate for a bunch of different values through out the exam, not exactly possible by hand given the fucked up non linear equations you come across in Chem E.

Also OP, think if logically this answer / units make sense like mentioned earlier.

Where do you get a TI-83 for 13 dollars? TI 86 is $17 on Amazon

When you get to a certain point, its implied that you are a master at doing basic arithmetic and algebra, and the advanced concepts are the focal point, so its a waste of time to work through all that by hand when you could be learning more advanced concepts.

Please try finding the determinant of a 6x6 matrix by hand, faggot.

First of all it is recommended that you get a graphical calculator like the Texas Instruments TI-Nspire CX, so that you wont make mistakes, because with basic calculators mistakes are often made for they aren't so advanced. And everyone makes mistakes, but in research mistakes shouldn't be made because one small mistake can change everything, but it happens sometimes i think, but not very often, but you should double check the answer so that there is not a mistake and that's how you don't make mistakes. The most common mistake is that you do something once but don't check so always check

Tbh if you need a calculator for exams you're going to a shit tier uni.

Physics here btw

If a student has demonstrated the correct problem solving process, but has a botched numerical answer due to an arithmetic error then who gives a shit. If they're doing something clearly retarded and have no idea what they're doing, then into the trash it goes.
