## Google: always-on calculator available

If you have a web browser running and need a quick calculation, you don’t need to call any other app. Just open Google and enter an example. If you set Google as your default search engine, just type the formula in the address bar. It’s cool that it also works in cell phones (smart speakers …) and in combination with voice recognition, so just give an example.

######

Google Calculator

If Google realizes this is a mathematical entry (and it must be admitted that it’s relatively fine in that respect – it also accepts the “x” as a multiplication, you can type “plus”, etc. in place of the + sign). Then the Web Calculator displays primarily clear results. In addition to the formula, it can also be called by searching for the word “calculator”.

Google Calculator correctly calculates the priorities of operations and can work with parentheses. Basic equipment includes calculations of percentages, powers and roots, and logarithmic or exponential functions. There is also a history of the calculations made.

### Positives

- Easy calling
- Available jobs

### little

- It does not deviate favorably from the line

## HP Prime: the classic for the insiders

The HP Prime Calculator is based on the classic hardware calculator of the same name, introduced in 2013 by Hewlett-Packard. She is also the author of an app for Windows PCs – it’s available in a limited free version, or in a Pro variant for a bold 569 kroner.

######

HP Prime

HP Prime is primarily aimed at students in the technical fields, for whom it will also offer advanced accounts and job graphs. From a visual point of view, we prefer to call this app an original calculator simulator.

The calculator is literally “stomped by jobs”, but it is worth studying to reach its full potential instructions. After all, the environment, the method of control and access to some functions are atypical in many ways. But if you have an HP calculator, you will feel like a fish in water in this program.

### little

- Complex control
- Paid copy

## Calculator X8: for nostalgia

The Dutch calculator Gergely Orosz is behind this calculator. Its X8 calculator is available in the Czech Microsoft store under the name Kalkulačka X8 and in the description you can read that it should be *“The most beautiful and feature rich calculator available for Windows 8. There are 3 features to choose from, and the calculator can be used in scientific or normal mode.”*

######

Calculator x8

The application is free without any conditions. The user interface is improved to control the touch screen, but you can also work with it with a mouse or keyboard. Retro fans will enjoy two alternative graphic themes that evoke the look of Calculator from Windows 95 and Windows 7.

The user interface is compatible with a standard scientific calculator. In addition to the basic arithmetic operations, in which the priorities are respected, there are parentheses, powers, roots, factor and logarithmic and trigonometric functions. A great bonus is a simple memory with the possibility of addition and subtraction, and some may miss the history of calculations.

### Positives

- free
- Graphic themes
- Understandable user interface

### little

- Account history is missing

## Wolfram Alpha: a data encyclopedia, a calculator without a keyboard

Wolfram Alpha It is a very different calculator. She is so smart, one of our colleagues once described her as the central brain of humanity. In fact, it is much closer to a search engine and has so many functions that most of the title page is occupied with help organized into four basic categories: math, science, technology, society, culture, and everyday life.

The only thing it doesn’t have is a keyboard. Queries are entered in a single field, and they can also process a text query without the correct form. If you want to take a quick look at historical Apple, Microsoft and Google revenue and compare that data. Without Tungsten, you’ll have to read the economic results, but WA in a condensed formula will respond right away. Try to go in for an example Apple, Microsoft, and Google Revenue 2000-2020.

The search engine takes data from reliable sources, and you will find a list of each result. When you do the calculation, it plots any function and shows the procedure for the solution. … but only in the paid version. The Pro variant costs $ 5.49 per month, the Pro Premium without a penny is $ 10, Students have a discount And available Mobile applications, For which you pay one time.

Try, for example …

## A super calculator: with its own screen

Another free alternative (but with a banner) is Super Calculator with a somewhat unusual user interface. While the basic operations are available in the button block on the right side of the screen, you will find a list of advanced functions on the left.

######

Super calculator

An interesting feature of this calculator is the “display”, or rather the way of displaying accounts. For example, fractions can be entered in the usual form for mathematical assignments – that is, as numerator and denominator – which is clearer than simple sequential entry. The ability to edit data already entered on the ‘screen’ is also useful.

In terms of the available functions, the best option is to work with memory. There are also no two factors or a button for the percentages calculations. During the quick test, the super calculator froze several times and sometimes fell.

- Falling and Freezing
- An extraordinary user interface

## Calculator⁺: with the history of mathematical operations

Calculator⁺ from development studio Asparion is a scientific calculator for Windows with a number of functions. Offers the possibility to choose from different graphic styles, color adjustments, and smooth window magnification (unfortunately windows only, not calculators as such).

######

Calculator⁺

The functional equipment is poor. In addition to the basic arithmetic operations, it only offers trigonometric functions, factorial, powers, roots, and percentage calculations. A great bonus is the database of mathematical and physical constants, so you don’t have to search for tables. Another strong point is the possibility to share the score or the entire account, and there is also a record of the operations that were performed.

### Positives

- Personalization options
- Mathematical and physical constants

## Mathway: Clicked in a web browser

At first glance, the Mathway web app works as an advanced scientific calculator. However, it is actually a complex mathematical application that is very well prepared and deals with a wide range of problems, including equations.

######

Mathway

It is possible to enter with the mouse, but you can also use the keyboard. However, the main feature is the chatbot-like functionality, which will help with correct input. For example, if you want to calculate a quadratic equation, just enter “x” and the whisper will instantly introduce “x” as an option.^{2}“.

After entering the equation, it presents several options for what it can do – for example, in the case of a quadratic equation, calculate the discriminant or compute the roots in several different ways. In addition to the result, it also offers a detailed calculation procedure, which you will definitely appreciate when learning or doing homework.

### Positives

- Chat bot
- Equation calculations
- Simple control

## Cal Scientific Calculator: No money, no ads

The author of the free scientific calculator Cal The Scientific Calculator is Colombian programmer Olger Rosero. It’s betting on a slightly discreet design, which is definitely not harmful in this case. Most buttons have secondary functions that are called by the button *Transformation*.

######

Cal Scientific Calculator

I consider the lack of keyboard support the biggest hurdle, you have to type everything with the mouse or the touch screen. On the contrary, I will commend the ten memory places where the intermediate results of the calculations can be stored and recalled later. In addition to arithmetic operations, there are calculations with percentages, trigonometric functions, logarithmic, factorial, powers, roots, and parentheses.

### little

- Keyboard support is missing

## Desmos scientific calculator: fractions like on paper

Desmos Scientific Calculator is a web-based application that provides a somewhat more complex user interface and a wider range of features than what Google Search Calculator provides. A great site, for example, is the ability to enter fractions and display results as a “numerical denominator”.

######

Desmos Scientific Calculator

The user interface can be controlled with the mouse, but accounts can also be entered using the keyboard. There is support for priority math operations, parentheses, and basic math with percentages. You can access other advanced buttons by clicking on the section *func*.

In terms of functional equipment, it is one of the most advanced calculators on the Internet. Displays *Mathematics tools* Hides other options, such as a special calculator for drawing graphs or a calculator for matrix calculations.

### Positives

- Simple control
- Fraction display method

### little

- Elaborate user interface

## Calc Pro HD: Pay for the best

This might sound surprising, but there are also paid calculators for Windows. Calc Pro HD can be downloaded from Panoramic Software for free, but is paid in the app. The full version will cost 229 kr, but you can try it for free for a week.

######

Calc Pro HD

This is definitely one of the best alternatives to the default app that you will find in the Microsoft Store. The application environment is executed in a modern spirit – it is square and filled with pastel colors. Ten calculators of various types are available in one application.

The basic equipment lacks brackets, which (along with many other functions) can be found in a scientific calculator. There is also the ability to convert numbers between different systems and the ability to graph jobs. It also includes a unit converter, currency converter, and several single-purpose calculators (such as interest or mortgage calculations). Only translation into Czech is lost to perfect perfection.

### Positives

- 10 Calculators in One
- Simple user interface
