What is a good graphing calculator?
What i I am asking is ... Ok I need a graphic calculator
Is it worth it to shell out the $$$ for TI-89 now to future proof or get a TI-83 and buy a TI-89 if I need one....
TI-89 not worth the extra $$$...
TI-83 overpriced, old and too slow.

Rounding Numbers
Rounding Numbers
A rounded number has about the same value as the number you start with, but it is less exact.
For example, 341 rounded to the nearest hundred is 300. That is because 341 is closer in value to 300 than to 400.
