Most of these calculators can only hold 5 (or was it 4?) numbers in its stack (whenever you click enter, it stores the number in a stack so later on when you do + or another operation, it takes the number from the most recent stack and does the operation). On #65 problems, the test writer sometimes makes it, when doing the problem left-to-right exactly as written, use more than 5 stacks so your first entry is gone and therefore you would never get the right answer. When you have a fraction or something simple and added/subtracted/etc. to a complex expression, you have to manipulate it so you can put in the complex thing first then incorporate the smaller/simpler expression. Hope that helps for #65s.

I also think that TI-89 is best.
I have the 32/89 combo! :D
Unfortunately, that means no excuses.
