**TOMSLEAD** – The *scientific* calculator is a calculating tool that is usually used by students majoring in science and other fields of science, for example for statistics, there is even a sophisticated *scientific calculator that can do simple programming.*

Several well-known brands, such as Casio, Deli, and Joyko, have released a number of scientific calculators with various types, specifications, and prices. For those of you who are looking for a scientific calculator product, this Tomslead article will discuss in full how to choose, product recommendations, and how to use it.

**How to Choose a Good Scientific Calculator**

*The scientific* calculator has functions to help various complicated calculations, such as trigonometry, logarithms, fractions, limits, exponentials, and geometry, which can be completed faster with this calculator. Therefore, this type of calculator is equipped with more complex buttons and is also used by engineers, teachers, scientists, and professors. However, to get the best *scientific calculator* on the market, you need to consider the following points.

**1. Choose the type of calculator according to your needs**

At least currently there are three types of *scientific* calculators , namely standard, programming, and graphical types. The standard type calculator features many functions, such as fractions, exponents, logarithms, trigonometry, and calculus. Of course, the number of functions available on each brand varies, but this type is most suitable for use in schools because it provides a variety of basic functions in mathematics.

Next there is a standard *scientific* calculator that has a programming function in it, so it is also called a programming calculator. Indeed, this calculator is not as sophisticated as a computer, but it is reliable enough to do basic programming. Thus, it will be of great help to you to set up the necessary calculation program in advance. However, this type of calculator is still rare in Indonesia and the price is quite expensive.

The third type is a graphical *scientific* calculator that can be used to draw simple graphs. This type of calculator is best used for statistics, for example when drawing scatter charts and bar charts. Interestingly, various graphing calculator products are now equipped with color LCDs and can simulate functions using the graphs installed in the calculator. One well-known calculator brand, namely Casio, has released a calculator that can display graphs, but the price is still quite expensive.

**2. Adjusting to the field of knowledge occupied**

In addition to the type, the scientific calculator that will be purchased also needs to be adjusted to the field of study occupied, be it engineering, science, economics, mathematics, or other fields. *On the market, there are scientific* calculators that only contain 100 functions, there are also those with high specifications of more than 700 functions, but most of the standard calculators have around 400 functions. When you know what functions are contained in the calculator, you can adapt it to the field you are concerned with, so you will avoid buying the wrong calculator.

**3. Verify the scientific calculator display**

If you are used to using a *scientific calculator,* you can choose a calculator with a conventional display. This calculator is designed with a special format to display its functional calculations and was commonly used until the 2010s. However, because the appearance looks 'old school', this product is not suitable for use by beginners because errors can occur when entering data and calculations.

As for beginners, you should choose a *scientific* calculator with a natural look. This calculator displays formulas and numbers according to mathematical equations written in the book, so it will minimize *input* errors and calculations performed.

**4. Consider comfort and energy sources**

There are many things that affect the convenience and comfort of a *scientific calculator,* including size, screen display, ease of pressing buttons, and compact form. If you have to carry the calculator everywhere, then choose one that is less than 15 cm long and less than 10 cm wide so you can put it in your clothes pocket. But if you want a calculator that is pleasing to the eye, for example for people with farsightedness, then a calculator with a large screen size is the right choice.

After confirming the various factors above, you can also consider the energy source used in the *scientific* calculator that will be purchased. Now there are many calculator products that use two kinds of energy sources at once, namely batteries and solar power, so there is no need to worry if one of them runs out of energy. If the battery energy is running out, just activate the solar mode as a power source. Conversely, if there is no sun as a power source, the battery will keep the calculator working.

*Usability of the Basic Keys on a Scientific* Calculator

*Usability of the Basic Keys on a Scientific*Calculator

Using a *scientific* calculator is somewhat more complicated than a regular calculator. Hundreds of functions that are present in scientific calculators may confuse beginners, but if you already know the use of each of these functions, this calculator will really help with various difficult calculations. Here are some of the basic uses of the buttons on a *scientific* calculator to help with calculations.

- M+ (Memory Plus) to add calculation results to calculator memory.
- MR and MRC (Memory Recall) to search for results that have been stored.
- M- and MC (Memory Clear) to clear numbers stored in the calculator's memory or set the memory to state 0.
- C and CE (Clear Entry) to clear the last input incorrect number.
- Min to save all calculations that are on the screen at a moment's notice.
- GT (Grand total) to display the total of all counts in memory or to perform a continuous count. For example, when calculating 5+5+(4×2) = 18, add 5+5=10 and store 10 with M+, then 4×2 = 8 and press GT to get the result.
- AC (All clear) to clear all calculation results on the screen and at the same time
*reset*all functions that have been entered, but will not clear calculations that have been stored in memory. - EXP (Exponential) to calculate exponentials.
- Shift to access additional functions available on the calculator.
- Auto Review to display the calculation results automatically according to the sequence, so that financial report calculations can be used using a calculator.
- Recheck to re-check the calculations that have been entered. It is usually marked with 1
*beep*if there is an error, while there is a 2-time beep at the end of the calculation if it is correct.

However, each *scientific* calculator brand has a different button name, even though the function remains the same. One example is that some calculators use the MR button for Memory Recall, but some use the MRC button. Both have exactly the same use, only the symbols are different, and that often makes users confused. Therefore, various brands of scientific calculators are generally equipped with manuals so that users are not confused when using the calculator.

**Conclusion**

To perform quite complex calculations, for example statistical calculations, engineering, physics, or other fields of science, a scientific calculator is needed so that calculations can be carried out quickly and accurately. This article has discussed in full the workings and recommendations of various brands of *scientific calculators,* including the use of some of the basic buttons on a scientific calculator.
