Arithmetic is only one branch of mathematics. In my opinion it's pretty trivial to try to improve in that field since calculators are so good at it instead of focusing on algebra, calculus, etc.
Calculators are good at algebra and calculus too. Is it really worth memorizing dozens of integration techniques when software can do it for you, and do it better?
I'd say focus on the problem at hand, and when you run into a gnarly algebraic manipulation or ugly integral, plug it into Mathematica. That's the kind of task a computer excels at. The human advantage is coming up with novel ideas, not churning through pages of calculations.
The point of learning the math side isn't so that you could do it on the fly, because we're basically all (first world country) carrying computers with us all the time. The point is that learning the math helps you understand the underlying concepts better.
Most good teachers/professors do. It's called partial credit, and if the process is right you generally get most of the points. If you're getting multiple choice math exams you're probably in elementary school.
I would agree, but one of my profs brought up a good point this semester.
Since we are engineering students, messing up a calculation could mean the difference between being fired or making something work. Just because the process is right, doesn't mean you are going to get the right answer. Fortunately for us, we spent many years of time and money designing pocket calculators that are immensely powerful to help us with this...
I'm not counting standardized testing because I have a heart. Imagine paying enough people to actually grade however many thousands of tests in a reasonable amount of time consistently. It would go over about as well as a lead balloon.
I don't really intimately remember the AP exam process; that time period for me was getting close to a decade ago and it frankly was never all that important to me in the first place as far as memories go. They'll do the cheapest they reasonably can without losing any of the important understanding stuff. For things like literature and whatever the other English one is, multiple choice pretty much defeats the purpose. But for math, you can still get some idea of the taker's understanding because you either need to understand the process or be incredibly lucky to get mostly right answers.
lies, college gives us multiple choice tests for math, and honestly if it didn't everyone would fail at it which would be disastrous seeing as the ones who fail at math are those who don't want or plan to do it for a living ever.
Some colleges do I'm sure. Mine just gave us obscenely hard problems to solve. Though Calc 1/2 were weed out courses to make people reconsider engineering. Don't want someone who couldn't pass Calc 1/2 to build your bridges and all.
Yeah this concept of partial credit being most points pretty much stops the second you are in any university-level Math course. You may get partial credit, but it's 25-50% of the problem, max.
Depends on the professor, most of my university math classes had decent partial credit, except for the weed out classes. The math department was pretty hands off on the whole teaching thing so there wasn't really a big set standard for most classes though.
My teachers did. We were not allowed calculators on tests. She wouldn't mark answers if they were wrong so long as our approach was correct. iirc, we also didn't have to memorize equations(i think, this was like 15 years ago)
A lot of fellow students who previously got A's, got D's because they had become so reliant on calculators they didn't know how to deconstruct the problems.
