### Buying Guide: Important Features That Matters

If you are shopping for a non programmable calculator, you face the challenge of buying one of good quality. To be sure that you have one of good quality, you must be sure of certain features. When you open an internet page advertising these types of calculators, don’t be pressured to buy the first product you see at the top of the page. Take time to go through the list and consider what your needs are. Here are some features you should be looking for:

Type: There are various types of calculators, but you’ll want the non programmable type. After confirming that it is the type you want, think about the size you need.

If your need warrants you to carry a calculator around more often, the handheld type will do. As an engineering contractor, a pocket-sized calculator is all you need. If you are a student and you only need a calculator at home, any size will do as long as other features are complete.

Function: A good calculator must be able to perform simple mathematical operations like addition, subtraction, division, and multiplications. In addition to these basic functions, they can also do simple currency exchange, percentage tabulations, taxation, and they must be able to recall history.

Since these are the basic functions you desire in a non programmable calculator, make sure they can perform these functions before paying for one. Don’t settle for less by accident -- some manufacturers promise various features that may not exist, so you should test them well before you pay.

Speed: If the calculator processes simple calculations fast, you will get things done quicker. The speed also comes into play when you have to enter a long series of numbers. The rate at which the speed is measured is lines per second, and this must range between one and a half lines per second to eight lines per second.

To also make sure that calculations are done fast, there are dedicated keys on the calculator that help to get a total figure without having to punch more keys. Such buttons include the square root key, the backspace key, the plus/minus key, and so on. These special keys are there to increase the speed of operation. Check for these special keys before buying any available model.

Display: Calculator displays come in three positions, these are “fixed,” “angled,” and “adjustable” positions. Many users find the first two easier to read, while others prefer the ones with adjustable display positions. You get to decide which suits you better.

You also need to consider the number of digits it allows on display. The greater the number of digits displayed, the better your calculator will be. Some modern calculators can display twelve digits. Take note of this feature when searching for the best non programmable calculator.

Price: Since the design and manufacturers of various non programmable calculators differ, it is expected that the price will vary. The complexity of some models may also make them a bit pricier than other models. However, most non programmable calculators are affordable, and with a careful and relaxed search, you will find just the right one that fits your budget.

#### Final Verdict

Many engineering students prefer non programmable calculators, because they tend to last longer than other types of calculators. You can use it for the duration of your academic programs. No wonder it is important to buy one of the best available. They are not just useful for academic performance but are also helpful for research and development.

If you are planning to take professional mathematics exams, you also need the non programmable type of calculator. While investing in a good calculator may not be easy, you should be sure to stay within your budget and requirements when making your choice.
