im in accelerated math and i still do that... well, i'll probably enter 5+2 instead. calculator for me is like paper and pencil.
sometimes i can work out entire problems on the calculator without ever hitting the "enter" button.
but as for other basic arithmetic, hehe. I failed math one year. 4th grade. we had big tests testing the multiplication tables. they were TIMED. i could never do more than about 30 of them
in the 10 minutes we were given. redface
hey, but 2 yrs later, i was recognized in some statewide math competition that allowed calculator usage. xp

bit188 *snip* Secondly, application: will you ever need to factor a second-degree polynomial (not counting you engineers and physicists out there)? If not, then why are we teaching these ridiculous "word problems"? We need to teach real application -- let's introduce some algebra based physics. *snip* Surely algebra based physics would include stuff like factoring second degree polynomials? Also, while I'm not that dependant upon my calculator, I heart my copy of Maple. I can live without it, I would just rather not for some problems.

Calculators. So funny.
All my friends are pulling out calculators to figure out some problem in Economics and I've worked it out before they've finised typing it in the calculator.
I mean in highschool we were taught how to do everything on our calculator, but when you get to university you almost don't need it (though its useful for working out things you used to have to use Eton tables for)
My maths tutor has this great hate of calcultors. He is always telling people to put them away and think it through.
I guess that's the difference between highschool maths and university.
At highschool they're trying to just teach you enough to get the basic requirements, while at uni they are actually trying to turn you into mathematicians.
I wish I had been here since I was thirteen, instead of sitting in that class with all the kids creating havoc and thinking, I learnt all this stuff YEARS AGO (thanks to my briliant teachers at primary (elementary) school)

One of my professors completely outlawed calculators. If you were caught with one on a test, you failed it unless he specifically said you could use one. Oh, the tables... I loathe those tables... that's probably the one reason I'm not intent on destroying all calculators.

A calculator is not a normal tool used for integrating something. In other stuff though, physics perhaps, in which you actually care what answer you get for different values, calculators are quite useful, as they save you using your slide rule to work out ln(√3).

That is true. Won't disagree with you there.

I was sitting in on an Alg I high school class today... it was horrible! These kids don't even get squares and square roots. The teacher spent the entire hour saying "It's when you multiply it by itself, darnit!" I think one kid got it. Thank jeebus the next hour was Pre-Calc. Finally, some bright ones. I almost murdered one of the freshmen. crying

I almost murdered one of the freshmen. crying Hm. I am also doing teacher observation. I would not be so quick to call some kids "the bright ones". In very nearly every situation I've seen, the reason a child doesn't understand algebra - or anything logical/mathematical/scientific - is a deficiency in the teacher not addressing the previous experiences of the students. That this teacher couldn't find real-world examples, or other ways of stating the issue, or *anything* that these students could relate to...

The kids actually don't want to learn. They'd prefer to sit in the back of the classroom and chatter all period without paying attention. They aren't trying to understand, so what's the teacher going to do? It's not that they're actually trying and failing, it's that they're content to not try in the first place.

In high school, over 90% of my classmates used calculators on every problem. I was one of the few who did all work by hand then checked it on a calculator.
