**Buy Scientific Calculators for Easy, Fast, and Accurate Calculations**

If you are a math, science, or engineering student or professional, then difficult and complicated calculations are inevitable. Apart from numbers, you have to deal with formulas of algebra and trigonometry that can be time-consuming without a scientific calculator. The scientific calculators are electronic calculators, and they are mainly used in mathematics, science, and engineering for professional use as well as academic purposes. You can buy scientific calculators online that are made and sold by various brands, such as Casio, Abdullah, Bambalio, and Caltrix, among others. On online shopping sites, you can buy a scientific calculator after reading user reviews, checking ratings, and comparing the prices of different models and brands.

**Before buying a scientific calculator online, here is all you need to know: **

**History of Scientific Calculators**

The first scientific calculator was released in the year 1968 by Hewlett-Packard, named HP-9100A. It was a programmable calculator that is often regarded as an early computer. HP built the 9100 series entirely from the discrete transistor logic. It was also the first personal computing device that used the CORDIC algorithm for computing trigonometric equations. And, it was also the first calculator that was based on the Reverse Polish Notation (RPN) entry.

**Use of the Scientific Calculator**

These calculators come with many buttons that let you work with different kinds of problems involving different types of numbers. Using this calculator, you can work on trigonometry problems, scientific numbers that involve a multiplication by 10 to a certain power, Pi problems, logarithm problems that have base 10 and the natural base, and probability problems that have the factorial function. Scientific calculators are also used for some astronomy, chemistry, and physics problems.

**How to Choose the Right Scientific Calculator?**

When it comes to buying a scientific calculator, you can either buy a Casio scientific calculator or pick one as per your specific requirement. If you are a student, looking for a reliable calculator for academic use, then Casio has many options for you. In case, you need a calculator for advanced use, then you can buy one as per your needs and requirements. From the point of view of calculation, a scientific calculator is ideal for algebra, geometry, analysis, and geometry concepts.

**Using a Scientific Calculator**

If you have not used a scientific calculator before then the first thing you should do is read the manual for a better understanding of your calculator and to know how to make the most of it. The number keys are easy to understand and navigate, however, it might take some time to get used to the other keys, such as keys for the trig functions, square root, and 10x, among others.

Scientific calculators are available in different sizes for your convenience. The display size also varies with the size of the calculator. Almost all scientific calculators are portable, and you can easily carry one in your backpack or handbag. So, login in to your favorite shopping website and buy a scientific calculator online for yourself or to gift to a math or science enthusiast.

**Make Calculations Easy with Scientific Calculators**

Had it not been for the limitations of an ordinary calculator, the scientific calculator would have probably never been invented. To stop complicated mathematical functions from complicating lives even more, American multinational IT company Hewlett-Packard, better known as HP, came up with what was called the world’s first scientific calculator in 1968. It was called the HP-9100A. But, it wasn’t quite convenient for one to carry the HP-9100A around, so HP put in about 4 more years of hard work and gave the world its first handheld scientific calculator - the HP-48. Priced at about USD 395 in 1972, the HP-48 was a mathematical luxury that only a few could afford. However, that’s not the case today. Nowadays, we have much advanced calculators that help us solve problems in mathematics, physics, science and engineering without making much effort. These calculator models enable you to solve equations or problems that involve fractions, complex numbers, trigonometric functions, binary, octal and hexadecimal calculations with ease. If calculations form an integral part of your life, then it is high time that you bought yourself a calculator. And, if you have been planning to buy one, then here are some of the aspects that you must get an idea about before buying a calculator:

**Mathematical Features** - Whether you have already been using a calculator for a long time or you are a new user, it is important for you to know what functions you are going to be using. If you don’t know that, then you may end up buying a calculator that doesn’t have those functions. The outcome? Tremendous amount of regret and no shoulder to cry on. And, that’s why it is essential to know those.

**Physical Features - **Now, if you are buying a scientific calculator, then you’d want it to last long, wouldn’t you? And, in that case it is better if you check for certain physical features, such as display, entry system logic, RAM, redefinable keyboard and menu keys, in the model that you are considering to buy, so you don’t have to buy a new calculator anytime soon.

Here are some of the most sought-after calculators that you can consider:
