I know it's just a number cruncher, but I feel like I'm always missing this in practice and in competitions. Can anyone shed some light on me?

Same problem, and I would bet you are missing it because of your HP calculator, if you have one, which you probably do if you miss #65 a bunch. I am assuming this.
You know that your calculator has a stack, right? This is where it stores all the numbers once you press ENTER. The drawback to the HPs is that the stack can only hold a maximum of 4 numbers (I don't know why, they should've been able to store more than that), so that if you enter a fifth number, you lose the first number that entered the stack. When you work #65, left to right, you often reach a fifth number, which gets rid of the first number in the stack, making your answer garbage. For 65, work from the inside out, not left to right.

Yeah, I've noticed a couple of things, where, if you entire a fourth number, the first number you entered gets repeated three times in your calculator's memory. Strange...

I use an hp 35s if that tells you anything

by **BlasianAsian** » Mon Mar 26, 2012 2:32 pm

Ew. HP 33 is so much better.

Why do you all use HPs for the number problems? I use one TI-84+ for everything and it seems to work just fine...

What do you mean by "completely avoiding parenthesis"?

by **BlasianAsian** » Mon Mar 26, 2012 5:12 pm

You can switch around the numbers and do them in any order you like. And if you won't miss anything and get that annoying Error: Syntax thing.

ok, what stated and geometry do you guys do to get scores of 300? I mean most of you guys are better than me anyways...

Well at least you are not as lame as me...

by **BlasianAsian** » Mon Mar 26, 2012 7:37 pm

Well, mister I'm hating on HP33, (=D), the button difference is less than 1/4 of a sec. What's the difference?

by **smeag** » Mon Mar 26, 2012 8:25 pm

what are you talking about?

by **BlasianAsian** » Mon Mar 26, 2012 8:29 pm

Calculators? Look at above posts?

by **007math** » Mon Mar 26, 2012 8:37 pm

I love how the OP asks something but by a few posts down the topic of conversation has completely changed.

And to complement this digress: HP 33s FTW :D

by **BlasianAsian** » Mon Mar 26, 2012 8:55 pm

^^^^^^^Amen to that!^^^^^^^^

And you're right, 007Math, you are SO right, lol. We math people's minds fly around so much.

by **nsguy1350** » Mon Mar 26, 2012 11:37 pm

I hear that HP32Sii is best.
I also think that TI-89 is best.
I have the 32/89 combo! :D
Unfortunately, that means no excuses.

whats wrong with hp33si compared with hp32?
and ti-84 to ti-89

by **BlasianAsian** » Tue Mar 27, 2012 2:58 pm

I guess just use whatever can get you to state?
