## Scientific Calculator – Purchase Guide, Opinions and Analysis of Best Scientific Calculator.

When your accounts require more than a few simple calculations, a good scientific calculator can save you time, effort and a lot of work in everything you are considering.

For this do not forget to adjust the type of calculator to the depth of calculations you need, as well as to have products with the programming options and the functions that you need so that you do not lack elements with which to work.

We can achieve this, for example, with the Casio FX-570ES model , which has up to 417 functions and 40 scientific constants, in addition to various programming options with which you will be more efficient in your operation.

A model that, due to its easy use and its screen, is considered the favorite of the users.

Another interesting model is the Canon F-715SG calculator, which includes all the basic functions of a typical institute calculator, but enhanced with additional functions, which offers a very practical system, without having to spend too much on your purchase.

## What is the best scientific calculator on the market?

In order to perform complex calculations, it is necessary to have adequate tools, with which to work with security and confidence and that are capable of responding to the level of demand that we propose.

To make your investment a success, we present our guide to buy the best scientific calculator, with tips to adjust your spending and squeeze the functionality of the decided team.

**Shopping guide**

**Calculation capacity**

When it comes to making a comparison of scientific calculators we can establish several levels of operation.

The first level corresponds to the basic models, which have certain advanced calculation functions, but which also do not allow excessively complex calculations.

It would be the typical high school student calculator for example.

From this point of departure we find products with greater capacity, with a greater number of calculations and with many additional elements of which we will speak, due to their importance, in the third section.

Finally, we find models with a specific capacity or specific development.

These products are special for specific uses, offering applications specially designed for fields such as engineering, computer science, market analysis and other fields, being equipped with what these professionals need to operate without problems.

Obviously they are not an economical option, so they should only be evaluated if they really are useful to you.

**screen**

To be able to visualize and work more comfortably, it is necessary that the screen has the necessary dimensions and visualization capacity for it.

In the case of scientific calculators, the product usually includes a single-line screen with a series of superscripts showing the active functions or measurements at the time (degrees, radians, etc.).

As we are in need of more management, for example in models with programming or with more complex uses, the screen should offer at least two separate levels of line input, to expand the visibility of the formulas and elements that we are introducing, avoiding this errors in the introduction of them.

Finally, we find models with large screens and even color, which allow us to draw graphs inside from the calculator itself easily.

Obviously, the quality increases, but it also increases how much the product costs.

**Functions and programming**

Although it is something that we have already introduced in the first paragraph, given its importance we want to deepen it, because it is what marks differences between models.

If you only need to do some basic calculations, a basic scientific calculator will probably suffice , but if the thing gets complicated, the tool offers interesting options.

Among them are the programming functions, with which we can enter different chained calculations to be performed on the machine.

Some models can accept up to 25,000 programming elements. Another interesting calculation element is the ability to perform differential calculus, integrals or work with matrices, for example.

If the product includes these features, you will significantly expand your possibilities.

And finally, we talk about the constants and functions included in which are the basic elements of mathematics.

These elements facilitate the use and save having to introduce elements, so if the offer covers the ones that you will use frequently, much better.

## What is the best scientific calculator ?

Making complex accounts requires complex tools. Luckily, you just need to equip yourself with a good scientific calculator to complete those tasks you need to perform.

To make your search for a good calculator easier we present a selection of the best scientific calculators of 2018, with models of all types and complexity so finding a complex number calculator adapted to what you need does not become a problem without solution.

### How to use a scientific calculator

When studying at university or doing work that involves the use of equation and function calculations, a scientific calculator is ideal.

In this opportunity we will give you a general information on how to use a scientific calculator to perform your calculations efficiently and productively.

**Know the parts of your calculator**

Before using your scientific calculator, it is important to familiarize yourself with its parts.

For this, it is advisable to read the user manual to determine which are the basic keys, the scientific function keys, power button, screen indicators, among other interesting features to know.

**Put the battery in your calculator**

Most scientific calculators work with an AAA battery, which must be properly placed in the battery compartment.

Some models of this type of product, have a solar power supply combined with the use of batteries, this in order to save battery power.

**Turn on your scientific calculator and use it**

To turn it on, you must locate the ON button, which is usually in the upper right. When you turn it on, you will notice on the LCD screen the number 0 and the cursor waiting for the instructions that you provide, to place the formula or equation to solve.

You can start using your product doing basic operations, using the numeric keys and the key operations.

Each time you enter a number and a fundamental operation symbol, you can see on the screen how the equation is formed.

Next, press the Equal key and on the screen you will see the equation on the first line and the result on the second line.

To make more complex equations, you can place the sign – located almost always for negative numbers, the parentheses keys and those of scientific functions.

To raise a number squared, you can use the X2 key located at the top of the key panel.

If you want to raise a number to any power, first write the number, which corresponds to the base and raise the power using the isosceles triangle key without base.

You can also use the square root function; it is used by pressing the key with the square root symbol and the number, with the same key, obtaining the square root of said number.

**Use the fractions and functions in your scientific calculator**

To write fractions on your calculator, start by placing the numerator, which can be a number, an equation or even a complex formula, then press the fraction key placed on the left side identified clearly and write the denominator that can be equal of complex.

Scientific calculators have logarithmic, exponential, trigonometric, integral, limit and derivative functions.

To use this type of function, you must have a prior knowledge of what each of them means.

These functions are identified by each of their keys. With the user guide, you can study how to use them in detail.

**Use the additional functions**

The most competitive scientific calculators include many more functions. To activate them, use the SHIFT key and select the function you need, depending on the symbol or function name that is printed, generally yellow on the side or above the keys.

Once you finish using your calculator, turn it off and store it in a safe place.
