Business Calculator help...

**gococksDJS** · 10-30-2005, 08:37 PM

I have a physics exam in the morning and the bitch is worth 30% of my final grade. This is the first physics exam i've had in college where I can't use a graphing calculator, and I have to solve some long drawn out circuit equations as well as polynomials using scientific notations like 8.85e-12 and 5.00e23. These are easy to solve on a multi-lined graphing calculator, like a TI-84, but does anyone know how to enter them into a single line business calculator without the damn thing solving it as an equation? The one I have is a TI-30XA.

just use the natural log functions

**gococksDJS** · 10-30-2005, 08:48 PM

well they aren't always integers. I have capacitance problems where the charge is usually something like 2.453e-12 Coulombs and some of the capacitance values are in micro-faradays some pico-faradays and some milli-faradays and I have to calculate the resistance across a circuit with multiple switches and resistors, and it has to be for every possible combination. Of course, the units have to be the same to cancel out, and i only get 50min. for this exam so I was trying to find a way to enter these values quickly because the circuit problems alone take a while.

**gococksDJS** · 10-30-2005, 08:49 PM

and yes I know you can use integers for natural log functions.

**MyK** · 10-30-2005, 08:53 PM

nah, not with a business calc, you can use the brackets if that will help, but thats about it!

**gococksDJS** · 10-30-2005, 08:59 PM

This is a basic one, but our exam will have more complex problems with internal resistor batteries, resistors on the circuit and all this shit. This one alone has about 7 basic equations, and will take forever if I don't know how to use this damn shitty calculator.

**MyK** · 10-30-2005, 09:02 PM

sorry, i cant help you

**themamasan** · 10-30-2005, 09:06 PM

I am so glad I am finished with school.

Good luck.

It's kind of shitty that im not having trouble with the circuits, im having trouble with using a "primitive" calculator.

**lnvanry** · 10-30-2005, 10:30 PM

i couldn't agree w/ you more gococks...It pisses me off the we can't use graphing calc during standardized testing. I have to take my GMAT w/ a six function calc only.

give me a fucking break...is this 1980 still. When I have to solve operations statitics in my career am i going to be limited to primitive calc? Fuck no

**gococksDJS** · 10-30-2005, 10:35 PM

The thing that I hate is that having a graphing calculator doesn't give you the ability to understand circuits. When i first took basic circuits, I didn't know what the hell was going on regardless of what calculator I had. Plus the more advanced the circuit, the longer and more complex the formulas are, and writing the equations takes long enough, then I have to solve them on a shitty ass basic calculator.

WHAT!!!

your not alowed a calc for the gmat! only pencil and paper

**lnvanry** · 10-30-2005, 10:53 PM

you can have a calc, but no graphing or financial calc...

samething w/ almost all standardized tests. ACT,SAT,LSAT,MCAT

nope your wrong! no calcs allowed

**lnvanry** · 10-30-2005, 11:00 PM

I don't know how it is you live, but your are defintely allowed to use 4-6 fucntion calcs in all these tests in IL.

multiply, divided, add, subtract, exponents, square root.

no calculators on standadized tests!

**lnvanry** · 10-30-2005, 11:14 PM

sucks for you

where R U from

**MyK** · 10-30-2005, 11:16 PM

maybe they let people like you have calculators to help "level the playing field"

**lnvanry** · 10-30-2005, 11:17 PM

Ohhhh I just read you profile...Canada...That explains it.
B.C. right?

What Skills Does the GMAT Test?

The GMAT primarily tests four skills:
Endurance and ability to focus
You'll have to stare at a screen intensely and focus for nearly four hours. Keep this in mind when taking practice tests. Get used to working for many hours on end. Learn how to relax. The physical and mental exhaustion is part of the test's challenge. That's why we offer GMAT CAT practice tests. You should take as many practice CATs as possible to learn the test and to get used to the grueling experience.

Basic knowledge of grammar, math, reasoning, and argument formation
The second skill, a basic knowledge of grammar, math, reasoning, and argument formation, is covered in the later chapters of this online prep guide. No calculators are allowed on test day, so you need to practice doing basic math calculations.

Test-taking skills: ability to guess, work at an appropriate pace, and make decisions under pressure
These skills are covered in this chapter and throughout the online guide. Timing is a major part of test-taking skill, particularly for the GMAT CAT. Our patent-pending Test Pacer system will teach you the pacing interactively.

Problem-solving abilities
To improve your problem-solving abilities, the fourth skill, we have extensive information on reasoning techniques and math concepts throughout this online guide. When you get a question wrong, make sure to review our explanations so that you understand the conceptual error that you made in the question. You do not want to repeat the error.

anything else you want me tp clarify????

**lnvanry** · 10-30-2005, 11:23 PM

sucks for you canuck.

**ST240** · 10-30-2005, 11:24 PM

i dont get waht you mean....

if you wanted to do 1.5E-1 + 0.4E-1, you just go 1.5[EE]-1 [+] 0.4[EE]-1 [=]

If thats what you're asking. Theres gotta be better approved calculators that you can use at your institution.

Edit A calculator like this http://mcbuero.shopstudio.de/images/items/066656.gif is much better because it has a playback line at the top where you can see what youve put into it so far

just wait till you have to do impedance with shit in AC

No testing aids are permitted during the test session or during breaks. Aids include but are not limited to beepers, pagers, pens, calculators, watch calculators, books, pamphlets, notes, blank sheets of paper, rulers, stereos or radios, telephones or cellular (mobile) phones, stopwatches, watch alarms (including those with flashing lights or alarm sounds), dictionaries, translators, thesauri, personal data assistants (PDAs), and any other electronic or photographic devices or potential aids of any kind.

sorry dude, these are the rulse for the gmat, it doesn't change over the border! the gmat is ran by one firm who controls and scorea all the testing. therefore the same rules apply!

**maniclion** · 10-30-2005, 11:41 PM

Eng. notation always worked easier for me and I had a much more limited scientific calc, as far as micro, pico and millifarads just move your decimal places. You should be lucky you don't have to troubleshoot a circuit like a control board for a pure sine wave inverter.
