Is there a big difference between Casio and TI graphing calculators?
Q. I need a graphing calculator for my AP Calc class, but I'd like to spend as little money as possible. I noticed that Casio calculators are a lot cheaper. I just wanted to know if the price of the Casio is worth it, as I only need a graphing calculator, nothing fancy with games or anything. Do they break easily or have significantly fewer functions? Any huge differences? Should I invest in a TI calculator or will Casio be good enough?
Asked by Jeffery G - Fri Jun 12 17:50:15 2009 - - 3 Answers - 0 Comments

A. Based on what I've seen/heard, Casio calculators actually have several more features than popular TI-8x models. Of course, these extra features are what cause them to be prohibited on examinations, such as the SATs, ACTs, etc. The most popular calculator I've seen today is the TI-8x series, particularly the TI-83(+) and TI-84+. The TI-89 and TI-92 are also quite popular, but also have a Computer Algebra System, which allows them to solve variables in equations, something their predecessors cannot do. Because of this, however, the TI-89/92 are not allowed on certain exams. I know that it also depends on the teacher. Most teachers I've seen prefer the TI calculators as well, but this varies. Ask your teacher for more information on which… [cont.]

A. You know that other short cable with the 2 same ends that comes with your calculator? Connect that to both calculators. Then on yours go to 2nd then the buton with X,T,O,n and a list will pop up. Now your friend while you go to that they also need to on their calculator go to the same menu. Your friend needs to scroll over to recieve on the top.

How come using Yahoo home loan calculators it seems like I am paying way too much for my current home loan?
Q. Took out a loan 6 years ago for 90K at like 5.75%. I'm paying around $900/month on it over 30 yrs. The calculators on Yahoo though say I can get a 90K loan now at 6% and only pay $540/month over 30 yrs. What is going on? Did I just get taken to the cleaners somehow? Is there anything I can do?
Asked by mcslain - Fri Sep 28 14:21:04 2007 - - 4 Answers - 0 Comments

A. I agree with the others... Yahoo calculators is just P&I. Meaning principal and interest. Your payment that you pay is PITI (principal interest taxes and insurance). But still 900 a month on 90K doesnt make any sense. That is huge. That would make you paying close to 45% of your payment to things other then P&I. It should be around 20-25% at most. Are you sure your interest rate was fixed? Im trying to figure out why your payment is so high even calculating it with PITI. Its way way way high. Its been 6 years so chances are you dont have Mortgage Insurance. So you only have Taxes and Hazard.

Why the numeric pads on calculators and phones are the opposite of each other?
Q. I was just curious - why the numeric pads on PC and the keyboard on calculators are a total opposite of the phones? I mean, in one #1 is on the bottom, and in the second one #2 is on the top? Sometimes when I work too long with a numeric pad I have to find the numbers on my phone. Can we ever have it similar so it is not confusing? Thank you for all your input.

A. Hi, This is an interesting question. In fact I haven't even think about it at all. I'm not sure but this is my theory: the numbers, same as letters in the keyboard should be located depending on their frequently use. So in the keyboard you usually use numbers from 0 to 6; so they are located in the lower part of the num-pad. The numbers on the phone, if you see they are also ordened alphabetically (with letters inside), this could be a reason; the other I guess is the same as the keyboard: comfortably, you usually use numbers from 1 to 6 but normally you type them with one finger, you don't put your hand in the same position as in the keyboard and assign 3 numbers to each finger and that kind of things, that's why it is more comfortable… [cont.]

A. Solve using a system of equations. Let x = number of scientific calculators ordered, y = number of graphing calculators ordered. x + y = 48 (since 48 calculators total were ordered) 8x + 55y = 1888 Solve. I got x = 16, which would make y = 32. They ordered 16 scientific calculators and 32 graphing calculators.

A. I believe that calculators should be used very sparingly until probably about algebra 2. There should be a happy medium. It is very important for students to learn to use calculators and be comfortable with them. This is because when they get to higher level math, many problems are unsolvable by hand. However, if they use nothing but calculators, they will not even get to that higher level math.

Asked by tomassierra - Tue Nov 28 14:21:31 2006 - - 2 Answers - 0 Comments

A. Phones were set up the way they are, because on the old rotaries, the numbers started at the left top. They tried to stay with that system. With calculators, which were set up before the phones, the idea was to have to have the farthest reach for the high numbers. That way if you mistouched something at the starting point, you were in the smallest numbers

And when they are a stage of learning math skills that are more theoretical than computational. Calculators are a great tool, but the user must also know how to get along without one as well just in case. When my hypothetical child (read: I don't have kids yet) is in Algebra II learning how to factor polynomials, I would rather that he or she spend more time on the factoring of polynomials than having to spend extra time doing computations that he or she already has mastered.

A. In a nutshell, NO. While they display sales in your area, they are unaware of the specific property details and thus can't reasonably reconcile (adjust) these sales between themselves, much less to your home. It will give you a vague idea, but the spreads I've seen have been as high as 70%. This could inadvertantly whip you into a frenzy before you find out the actual, supportable value. Simply be sure, if you have any influence, to engage a competent appraiser.

A. Seems like you English teach needs to get tough as well. What is wrong with learning how to add, subtract, multiply, and divide? It is easy enough. When I go to the cash register to pay my bill, I know whether I was charged the proper amount, how much change I will get back, and generally I know which denominations of bills and coins I will receive. That makes it easier for me to tell quickly whether the young kid at the cash register did it right or not. More often as not, when it is a young person at the cash register, they screw it up. Older people usually get it right.

Asked by DianaC - Wed Jul 15 21:34:14 2009 - - 3 Answers - 0 Comments

A. There aren't any differences between two TI-84+ SE models. They're the exact same thing. However, it's probably likely that someone just accidentally placed the SE on a regular TI-84+ rack. The only major difference between the regular is memory, as follows: Plus Edition: 480 KB user accessible of 1 MB Silver Edition: 1.5 MB user accessible of 2 MB Other than that, they're pretty much the same. The Silver Edition, however, comes with a lot more apps pre-installed than the TI-84+ does. Though technically if you buy a TI-84+ all you have to do is use the cable and the disk they give you to download those apps from TI's website.

A. Our brains are amazingly versatile, but we find it hard to calculate in our heads because they can store only so many numbers. According to a famous bit of 1950s research by psychologist George Miller, we can remember typically 5-9 digits (or, as Miller put it: "the magical number seven, plus or minus two") before our brains start to ache and forget. That's why people have been using aids to help them calculate since ancient times. Indeed, the word calculator comes from the Latin calculare, which means to count up using stones. Mechanical calculators (ones made from gears and levers) were in widespread use from the late-19th to the late-20th century.

A. Unfortunately, the reasons AT&T / Bell Telephone picked the "1 2 3" at the top ordering versus "7 8 9" ordering which had previously been used in calculating machines are lost to antiquity. There appear to be no definitive answers. Only plausible theories. One plausible theory is that this order was chosen to slow down people who were very adept at using calculating machines so as to prevent overloading mechanical switches. I don't buy this one myself. I think the people promoting this theory are confusing this reason with the development of the QWERTY keyboard layout by Christopher Sholes who supposedly chose the layout to prevent type bar collisions in mechanical typewriters because of frequently used letters being too close to each… [cont.]
