# What is the most powerful scientific calculator

## Calculator comparison 2021

• Pocket calculators not only make simple arithmetic processes easier, they can also set up graphs, functions and equations.
• Most calculators work with rechargeable batteries, batteries or solar energy and have shock-resistant covers that make them handy companions for school, university and business trips.
• You can play your own software on programmable pocket calculators that facilitate mathematical processes. These devices have more storage space than others.

In the past, pocket calculators had hardly any functions and had no displays. The results were printed out by hand with a crank.
Since then the first electric pocket calculator developed in 1967 in Texas by the manufacturer "Texas Instruments" a lot has happened. At that time dhe first model with a microchip was still 1.5 kilos and was a big, thick box that printed out the results in a manner similar to a labeling machine. In the past 50 years, however, a lot has happened.

Hardly any other school subject divides students as much as mathematics: some love it, others hate it. No matter if math fanatic or not, everyone can agree on one thing: calculators make every task easier and the solutions obtained feel more secure.

But calculators are not only used in schools. In many courses of study and in every craft and business occupation Calculators are urgently needed in 2021 in order to avoid errors and the financial damage that often comes with them.

Pocket calculators are small and not only weigh about seven times less, but are also able to display graphs and functions and can come up with modern displays.

### 1. What types of calculators are there?

#### 1.1 Calculators for finance and simple bills

On the whole there is five different types of calculators.

Those who primarily like simple arithmetic Addition and subtraction, multiplication and subtraction would like to calculate, you probably don't need a calculator that can display graphs or set up functions. Generally z. B. any calculator with fraction and painting functions fitted.

Need a calculator for household, financial or retail billsAll you need is a basic calculator or a financial calculator. The differences are listed in this table:

Basic calculatorFinancial calculator

The Sharp "El-234S" is an example of a basic pocket calculator that can handle fractions, multiplications and all basic arithmetic operations as well as percentages.

For example, the "HP-BII" pocket calculator is a financial calculator in which, in addition to the basic arithmetic operations, there are also calculation methods in all financial areas.

cheapest calculator

Basic arithmetic, percentage calculation, tax calculation

intuitive handling and stable housing

suitable for business administration, accounting and statistics

Loan installments, interest rates, standard deviations, linear regression, statistical functions with statistical analysis possible

insensitive and suitable for business trips

no functions, graphs, diagrams etc. possible no equations and diagrams possible

slightly more complicated to use due to more functions

#### 1.2. Calculators for school, university and clear bills

Are you Pupil or student, deal with scientific mathematics or if you want a calculator altogether that eliminates the need to present your results with pen and paper, consider a graphing calculator or one scientific calculatorto buy.

These categories differ as follows:

graphical calculatorscientific calculator

The Texas Instruments calculator "TI-82-STATS" is z. B. a graphical calculator which is particularly suitable for diagrams and functions in addition to the existing basic arithmetic operations.

Casio calculators are classics in school lessons. The "FX-991DE-X" is also z. B. a branded scientific calculator that meets all the requirements of teaching institutions.

graphical representation of diagrams, graphs and functions

simply calculate sine, cosine and tangent

large display that simplifies the presentation

most of the options

Basic arithmetic, graphic arithmetic and some financial functions are possible

usable for every degree program
