The calculator saves you mental arithmetic and is quickly at hand whether you are calculating household costs or checking homework.

What is the best calculator for you? The purchase advice provides you with the most important information.

With the handy calculator you have a useful calculation aid with you. The device can accompany you for shopping or is used at school. The basic models are at least suitable for basic arithmetic operations. The modern pocket calculators from the tests have additional computing functions that should suit your needs. Science and finance calculators offer the relevant types of calculations.

Which calculator is your test winner depends on your work area. Apart from the functions, the format and the operating mode also play a role. Flexible and small calculators often work with batteries or solar power, while larger desktop calculators can be connected to the plug. The size of the device also affects the display, where you can read the numbers and some other information.

The selection of the best calculator is based on the calculation types, size and programmability. Depending on the purpose for which you are using the calculator, these aspects play a more or less decisive role.

### Types of calculations: Scientific calculators offer a larger scope

The basic arithmetic operations for the basic calculators are addition, subtraction, multiplication and division. Percentage calculation is often possible with simple calculators. A school calculator can also calculate fractions and roots. The calculation types for scientific and financial computers are somewhat more extensive. Here you have the option of converting currencies or calculating physical numbers. The functions of the graphing calculator are even more complex.

### Operating mode: battery or solar powered

Most calculators use solar or are battery operated. The solar-powered devices do not require a lot of light to charge, and the calculator use little energy. In general, it is sufficient to leave the calculator open in daylight. This makes the solar powered calculator particularly energy efficient. A battery lasts for a relatively long time, but it is necessary to change the battery after a certain time.

### Display: Graphing calculators offer a large display

The display on the basic calculators is single-line. By default, the small models display 12 characters, but for the representation of long numbers or many decimal places, there should be more characters. In order to show a fraction or complex data, the displays of the scientific calculators are broken into 2 lines. This gives you more space for the invoice and the subsequent display.

Graphing calculators have a particularly large display. As with the simple models, this can have backlighting. In addition to the simple numbers, other data that can be called up in the form of a graphic can be shown on the display with a relatively high resolution.

### Programmability: save calculations in advance

Mostly, only non-programmable calculators may be used at school. A programmable calculator can be compared to a computer, because here you can program the calculations as required. You can call up the program later from the device memory. You simply enter the simplified, automated calculation processes using the calculator keyboard.

### Best Programmable Calculator

- CASIO
- Number of Functions: 664
- Natural textbook Display expression same as textbook.
- 10-digit mantissa + 2-digit exponential display.

### Keyboard: Modern calculators also offer a touch display

In addition to the number field, there are function keys with plus, minus and other basic arithmetic operations. The professional calculators have significantly more keys. The best calculators for demanding arithmetic experts have a touchscreen. This is particularly worthwhile for the diagram display and for complex calculations.

When looking at the keyboard, you should pay attention to comfortable operation. This depends on one hand on the size and spacing of the keys, and on the other hand on the speed of reaction. When you type in numbers quickly, you want the keyboard to be as smooth as possible.

## The Differences with Calculators

Whether scientific calculator, graphing calculator or simple calculator – all model types offer advantages and disadvantages, which you will get to know in the following section.

### The simple calculator

The simple calculator helps you to check everyday bills. In addition to simple calculations, you can use it to perform percentage calculations and, in some cases, save individual numerical values. A simple push of a button is enough to switch on the calculator. Some turn off automatically when they are not used for a while, others have an on / off switch.

The cheap, mobile calculators are easy to use. You can see the symbols for basic arithmetic operations at a glance. The electronics are protected by a stable housing. Depending on the functions, these simple basic calculators are suitable for students. The handy devices are well protected from dust and bumps in a protective cover. They are typically non-programmable calculators.

**Advantages**

- Favorable purchase price
- Handy format
- Mobile use possible
- Partially suitable for school
- Energy efficient

**Disadvantages**

- Restricted functions
- Often only a one-line display

### Best Solar Calculator

### The scientific calculator

Compared to the basic calculator, the scientific calculator can perform significantly more calculations. It calculates angles, logarithms and statistics. If you enter the relevant data, the calculator will immediately display the result. The important additional functions include saving and editing the calculated numbers. If it is a programmable calculator, it may not be approved for exams. You should definitely clarify this at school or university.

The numerous scientific functions require a certain training period. Often you will only get to know the many possibilities after a while. Then you can use the full potential of functional and high-quality calculators. Based on the current tests and product descriptions, you will find out what each calculator can do and which model is suitable for your purposes.

**Advantages**

- High functionality
- Larger display
- For school, university and work
- Partly programmable

**Disadvantages**

- Relative expensive
- Not allowed everywhere (school exams)
- Training necessary

### The graphing Calculator

Graphing calculators can not only calculate and display simple numbers, but also diagrams. For this, these special models are equipped with a large display. This allows you to look at mathematical curves and other graphics and visualize the formulas. As a subcategory of the graphics calculator, the CAS calculator plays a special role, which makes complicated calculations easier for you.

In addition to the usual computing functions, the graphing calculators are often equipped with other math and geometry programs. The extended range of functions can also be supplemented if necessary if it is a programmable calculator. Compared to the simpler calculators, the graphing variant is often relatively large and not so handy. Nevertheless, they prove to be relatively mobile and practical calculators.

**Advantages**

- Diverse complex computing functions
- Often programmable
- Large, clear display
