## Cheap Graphing Calculator – How To Spend Under $25

Graphing calculators prices are an anomaly in the world of consumer electronics. How is it that a smartphone can become obsolete almost as soon as it is released, but a graphing calculator invented decades ago seems to steadily increase in price year over year. It can feel criminal to be asked to pay over a hundred dollars for such a primitive device luckily there are ways to score a cheap graphing calculator.

## Where to Find Cheap Graphing Calculators

**#3. Thrift Stores and Garage Sales**

Second hand shops and rummage sales have been great sources for me when searching for cheap graphing calculators. Unless the seller is currently in school or has a child in class they generally assume the calculators are worthless and price them accordingly. I was once able to score three mint condition TI-84 Plus Graphing Calculators for $2 each at a thrift store and they were shocked I was willing to pay them so much for such and old piece of equipment!

**#2. Buy a Used Graphing Calculator Online and Trade it in Afterwards**

This may seem like a no brainier but many do not realize you can buy a cheap graphing calculator calculator then trade it in afterwards, much like you do with your textbooks. When buying a used graphing calculator be sure to read the listing descriptions carefully and buy from a reputable site like Amazon. Then after your class head on over to the Trade-In Page and get most of your purchase price back. For example at the time of writing I could buy a perfect condition TI-84 Plus for $57.48 and trade it in for $32.65 bringing the cost of using a calculator down to only $24.83. Much better than paying the $100 plus for a brand new unit!

**#3. Borrow One From a Friend or Relative**

You will be surprised to find out how many graphing calculators are sitting in desk drawers never to be used again. Ask around, I bet you will be able to find someone who is not using one at the moment.

## Best Financial Calculator for CFA Exam: TI BA II Plus Professional vs. HP 12c

# TI BA II Plus Professional vs. HP 12c

The CFA Institute does not leave potential test takers many options when it comes time to choosing which financial calculator to use while taking the CFA exams. In fact there are only two models allowed(along with their variants) either the Texas Instruments BA II Plus or the Hewlett-Packard 12C.

One important tip that many recommend is to **BRING TWO IDENTICAL CALCULATORS** out of precaution. Batteries can die and buttons can jam and you will be dead in the water if you have to finish without a calculator. The examiner will not let you use a loaner calculator. Financial calculators are very cheap, there is no sense in taking an unnecessary risk.

The rivalry between HP and TI dates back decades and there are many who are sharply divided on the issue similar to the rivalry of Mac vs. PC, but the main difference comes down to something called Reverse Polish Notation or RPN, which I go into great detail in here if you are interested. But basically it comes down to what order you prefer to press the buttons on the calculator to reach the answer.

## TI BA II Plus Professional

Overtime RPN has fallen out of favor and Texas Instruments has come to be the dominant player in the calculator industry and many study guides now only include examples on how to use the TI BA II, and you will find most of your classmates use the TI BA II Plus or TI BA II Professional and it is most likely the calculator you are already most familiar with.

### Pros

- Familiarity. Widely used and easy to find established study materials.
- Capability to perform a larger number of functions such as Discounted Payback
- Affordable

### Cons

- No Reverse Polish Notation

## HP 12c

Many old school bankers prefer RPN since that was the standard while they were going through school and many were given the HP 12C which uses RPN as standard issue on their first day.

### Pros

- Uses Reverse Polish notation. This is a no brainer if you are a diehard RPN convert.
- Street Cred. If you show up with one of these everyone assumes you are a financial savant.

### Cons

- RPN again. If you have never used the HP 12c you should plan on spending a few hours getting to master the calculator. But many swear you should put in the effort due to the time saving effect of having to use fewer key strokes to get to the answer with an RPN calculator and every second counts on the exam.
- Price. Tends to be more expensive than the TI competitor but you may be able to pick up a used one HERE for far less. Be sure to buy one from a seller with near perfect feedback.

## Who wins?

It all comes down to what you feel most comfortable with. If you have never used an RPN calculator before then right before a major exam is not the best time to begin learning a whole new process and you should stick with the TI BA II Plus. However if you are already a pro with HP calculators then by all means stick with the HP 12C enjoy it, you earned the right to bask in the limelight.

## HP 35s Scientific Calculator Review

# HP 35s Scientific Calculator Review

This calculator is classic by many means. It has the look and feel of a serious machine, and the display of a traditional scientific calculator. If you are a loyal HP user, this calculator will feel familiar. The HP 35s Scientific Calculator is a Reverse Polish Notation (RPN) calculator, which means that it doesn’t require the use of brackets to define priorities for evaluation of operators. Some people are long time RPN users and absolutely swear by the method. Some newcomers claim that RPN is very easy to learn and worth the time. Others, yet, prefer to bypass the whole system and go with a more user-friendly and intuitive interface. The RPN mode comes in handy especially in a scientific calculator with fractions like this one in which fractions can be inputted in a variety of ways, as per the user’s choice. The HP 35s calculator is programmable, a huge plus for those who rely on pre-programming to facilitate everyday calculations, or speed up certain test problems. However, only a few programs can be stored since it limits the number of labels and variables to 26.

This scientific calculator with fractions makes it easy to view and perform both regular as well as mixed fractions. It features a fraction button and gives the user the choice to input the fraction using RPN or algebraic mode. Both modes will return the same result, the main difference is in the format of the input. This is more than just a scientific calculator with fractions, it performs advanced mathematics, especially the type required in scientific, medical and engineering professions. Engineers who are already familiar with RPN may consider this calculator a good choice for the NCEES PE and FE exams. Although, it’s not a good choice for everyone because of its interface, it does deliver on the math. Some features are made to facilitate common problems like two-variable equations. Enter and solve two equations with two unknowns simultaneously using the HP Solve application. Enjoy features like numerical integration, and complex number and vector calculations.

Without solar assistance, expect to change the batteries quite often. The physical design of the calculator is attractive to the serious type, and the buttons are ergonomic and feel easy and comfortable to the touch. A hard protective cover comes included with the calculator.

Unlike most recent scientific calculator models that display four lines at a time, the HP 35s only displays two lines. It also doesn’t feature the newly coveted textbook-like display. This is not the most intuitive or user friendly calculator, but it will certainly appease the more traditional user looking for nothing more than pure programming and mathematical power.

## Casio FX-115ES Plus Review – Casio Scientific Calculator

# Casio FX-115ES Plus Review

Casio claims that this new calculator is their most advanced scientific calculator to date. It is, in fact, especially when compared to Casio’s previous lines of scientific calculators. The Casio Scientific Calculator FX-115ES PLUS offers the newest trend in scientific calculators: the “natural textbook” look. Inputting complicated equations and reading outputs is made easier with this function because of the way the numbers are organized on the screen. For example, fractions look exactly as they would if written on a piece of paper – a numerator directly above a horizontal line and a denominator underneath. Pi is depicted symbolically and square roots are easier to visualize. This is a feature that helps tremendously during test-taking, especially if your mind is accustomed to viewing equations and examples from written texts. The Casio FX-115ES PLUS also holds previous entries and outputs in memory so that you can recall and modify current entries.

The Casio FX-115ES PLUS is a good choice for the NCEES FE and PE exams as its mathematical capabilities are sufficient for most Engineering demands, even more advanced ones. This calculator makes unit conversions easy since the most common unit conversions are pre-programmed into it. During a test, the last thing you want is to strain your brain for scientific constants; this calculator takes that pressure off by giving you access to codes for over forty scientific constants right inside its cover. Enjoy many other useful time- and energy- saving functions. Find the xth root, factorize prime numbers, calculate remainders, convert between metric units, calculate equations and inequalities, perform matrices and vectors, and use complex numbers among many other standard scientific calculator functions.

There is a major drawback to this calculator: its history is wiped when the ON button is pressed or when switching between modes. The calculator automatically shuts off after a couple of idle minutes, which is great for saving power during a long day of problem solving, but if you step away for a quick break everything input and calculated up until then will be gone when you return. This has been reported as its main issue by otherwise very satisfied users.

At 3.35 ounces, this calculator won’t add any burden to your backpack. Its keys are plastic and it comes with a hard cover for safekeeping. The price of this calculator certainly doesn’t reflect its enormous range of possibilities. For the low price, the Casio FX-115ES PLUS is a great investment for anyone looking to adopt and become familiarized with their first – or next – scientific calculator.
