What are the best calculators?
There are several types of calculators available on the market today. Some of them have been around for years while others were created recently. There is no right or wrong type of calculator; it all depends upon your needs and preferences. However, there are some basic guidelines that should always be followed when choosing a calculator:
1) Price : The higher the price tag, the better quality and functionality will be provided by the calculator.
2) Functionality : The more features the better.
A calculator with only one function is not necessarily any better than another. For example, if you need to do simple calculations then a simple arithmetic calculator might be just what you need. If however, you want to perform complex mathematical operations such as solving equations or calculating interest rates, then a more sophisticated calculator would be required.
Support : Does the manufacturer provide support for their product? Are they willing to answer questions or fix problems? Do they offer free updates?
Features : What additional functions does the calculator include? Is there a way to save your work so that you can access it later? Will the calculator allow you to export your results into other formats (such as PDF)?
User Interface : How easy is it for users to use the calculator and how intuitive is its user interface?
Size and Weight : How big or heavy is the calculator? Are you able to easily carry it around in your pocket or in a briefcase?
Portability : Will it run on batteries or will it require an electrical outlet to operate?
The following is an overview of some of the most popular types of calculators available on the market today:
Casio FX-115: This type of calculator is very similar to the scientific calculators of old. This calculator has a 10-digit display and can perform basic math functions. It has a built-in square root button and a percent key but does not have common functions such as logarithms, trigonometry or exponentiation.
Many people like this type of calculator because it is simple, reliable and relatively cheap.
Casio FX-CG20: This calculator is very similar to the Casio FX-115 except that it is slightly more expensive and has a larger display (12 digits).
Casio FX-991ES: This is one of the most popular types of calculators available on the market today. It has a 12-digit dual power display and allows users to perform complex mathematical operations. Its features include a graphic calculator for plotting graphs as well as a statistical calculator with features such as data editing, regression analysis and sorting.
One of the most important features of this calculator is that it can perform symbolic manipulations; in other words, you do not have to enter equations as formulas.
Hewlett-Packard HP-33: The HP-33 is one of the most advanced calculators available on the market today. It has a 12-digit display and allows users to perform complex math operations such as exponents, logarithms, trigonometry, calculus and algebra. It also has a built-in database and a programmable calculator.
One of the most important features of this calculator is that it can store information such as statistical data or programming instructions so that they can be used later.
Texas Instruments TI-30XIIS: This type of calculator is similar to the Casio FX-991ES except that it only has a six-digit display and does not have as many built-in functions.
TI-83 Plus: The TI-83 Plus is one of the most popular types of graphing calculators available on the market today. In addition to performing complex math functions, this calculator can also show graphs and provide numerical values for these graphs. This type of calculator has a 10-digit display and allows users to perform complex mathematical operations such as factoring and finding zeros.
It also has a built-in database that can store up to 25KB of text and numbers.
Laptop: If you want to use a computer-based calculator you could bring a laptop instead. These types of calculators can perform any calculations that your desktop computer can perform (just on a much smaller scale). The only major drawback to using a laptop is that they have a tendency to run out of power so you will need to have the battery charged or be near an electrical outlet when using it.
The following is a list of five of the more popular types of laptop computers available on the market today:
Apple MacBook: The Apple MacBook is one of the most popular types of laptops available on the market. Some features include an LED display, a removable battery and an optical drive. It also has a wide range of operating speeds, up to 2.4GHz.
Dell Inspiron 1525: The Dell 1525 is another very popular type of laptop. Some features include a 15.4″ display, a maximum operating speed of 2.0GHz and an optical drive.
It also has a removable battery and wireless capabilities.
Toshiba Satellite L505D: The Toshi L505D is a laptop that comes with a 15.4″ screen and a maximum operating speed of 2.2GHz.
It also has both wired and wireless capabilities and a built-in DVD burner.
HP Compaq NC6400: The HP Compaq is a laptop with a 15.4″ display and a maximum operating speed of 2.2GHz.
It also features both wireless and wired capabilities and a built-in DVD burner.
Fujitsu Lifebook E744: The Fujitsu Lifebook E744 is a laptop with a 15.4″ display and a maximum operating speed of 2.2GHz.
It also has both wireless and wired capabilities.
