The rounding on my calculator is often different than what is rounded on the answer choices. How many decimal places are we supposed to use on our calculators? I am using 4 at the moment. Thanks in advance.
I always did 5. I’m sure 4 is fine as well but I wouldn’t use 3.
I thought 3 was fine. Better than the 1 decimal place I was using before I figured out how to change it, 5 min before the exam.
set it to 9 so that it rounds when it can and gives full # when it cant. store values with the STO function for easy access. that way you dont have all those 0s for no reason, i dont see why anyone would do anything less than 9 for this reason alone
4 is pretty good
4 is pretty good.but i remember,for some calculations , u need it to set to 6 (Derivatives , i think)
I always used 4. But one of my students once pointed out (rather intelligently) that using 4 decimals means that you are effectivly using 2 decimals when expressing percentages in decimals. I still (rather stubbornly) work with 4, but it really doesn’t make a material difference.
