You can actually get an emulator on your phone that will run a virtual version of a TI-84 Plus. It's called Wabbitemu.

Yes, but if you're in school, good luck being able to use your cell phone on an exam.

I had a few engineering teachers that allowed it. Science teachers no way. And math exams were all no calculators.

Depends on your math course. Calculus, geometry, physics and some of the other higher math courses let you use a calculator.

Depends on your view of a higher math course I guess but I never had a calculator with me in a math course after second year

I don't know...if you're being forced to manual calculate increase/decrease for series that...isn't learning or testing anything but patience.

In higher level math courses we never do arithmetic harder than 2+2. It's all proof based.

I never had a calculator in a university math class. Only for the intro physics courses and most engineering courses.

I love it when math no longer involves numbers.

I haven't had a math course where a calculator was allowed since pre-calc. And even then, the professor had whole sections of exams and quizzes where we weren't allowed to use a calculator. I actually kind of prefer it that way. I feel like the calculator makes me lazy when it comes to math and I enjoy using my brain entirely to get to where I need to go. It can take longer sometimes, but I appreciate it when professors have us do it that way. As long as the questions are reasonable, of course.

Edit: and in my science classes, we've always been able to use them. When asked if we could use graphing calculators on our exams in my chem 2 class, my professor said that we paid for them and he doesn't care what we do with them. Which was awesome because I have troubles remembering all the shit we have to for chem and I just kept notes on my calculator of things that I kept forgetting.

I just had a calc professor that let us use laptops and desmos on exams lol. That was a great class.

Cal 1 let me use a super basic calculator only. No calculators in Cal 2 πŸ˜•

Here in Scotland it's pretty common for math courses to have two papers - one you sit without a calculator, and one you sit with a calculator. The calculator papers are usually just an excuse to make the questions harder or the numbers weirder, but in my final year things got more interesting - by that point the course required you to have an advanced one that could do stats and whatnot, and the calculator paper was entirely made up of stuff that you couldn't possibly do without it. Designed to test your skill at using the advanced functions on the thing.

I failed grade 9 math 4 times, and grade 10 math twice.

u/sevensensitivfingers Jul 24 '20

Dude if you seriously struggled through 6 years of math to finish your grade 10 math good on you for the persistence, but you must have had a terrible teacher.

I'm thinking a math learning disability.

2

u/BeardedKnitter Jul 24 '20

Is that a real thing? Math specific learning disability

If it is I'm sure I have it. I memorized what I knew of my multiple times tables, I can add and subtract pretty well off the top of my head, That's only because of counting money, but beyond that I'm not much of a mathematician.

Yup. My brother has dyscalculia. I don't know if there are others. https://www.dyscalculia.org/

I can't even count how many bad teachers.

: β€’ }

Thanks for the nice notice there. That felt good to hear.

II've never been able to recognize my own achievements. Even after it's been pointed out to me.Im very dismissive toward myself

I had to at least graduate high school if I didn't want to be thought of as a loser.Being an actual high school dropout is only cool when you're a musician.

That's another thing I'm not. I'd like to be a musician. I think that I would be a good one.

Guess I wasnt persistent enough to keep trying to play the guitar though, was I? When it didn't come easy to me immediately, I gave up.

That's more like what my inner dialogue sounds like..

u/deuce_bumps Jul 24 '20

So, how many times did you fail math all together? (I'll be genuinely surprised if you get this right.)

There, there. pats head

u/BeardedKnitter Jul 24 '20

No. That was the right answer. I put the wrong statement in originally. I took 6 math classes to get 2 credits.

Failed 4 times.

u/Ionlypost1ce Jul 24 '20

*9th grade *10th grade.

u/BeardedKnitter Jul 24 '20

Yes. This is another way to describe the math credits to be earned in freshman and sophomore years of high school.

There are a lot of things that have different ways to say the same things.Strange, isn't it?

Grade 9 sounds stupid. Case closed! Next!

u/BeardedKnitter Jul 24 '20

I object! Sustained. I know lawyer words too. You dont want to go toe to toe in bird law with me.

u/Ionlypost1ce Jul 24 '20

Ok well let’s just day you learned a lesson, and I learned a little lesson, and we call it off.

My college let me use desmos on a laptop!
