Imagine this:

You are an engineering professional, who needed to perform this calculation - 58,675,985 x 73,892,619?
Or this: 2.5^{4} + sin 63 + log 28

Or for that matter, any calculation that involves any scientific calculations, which includes exponentials, logarithms, factorials, trigonometrical, imaginary and complex numbers, matrices, fractions, decimal arithmetic, and a lot more!

Sadly, we are not equipped with an amazing mental calculator like the renowned mathematician Shakuntala Devi. This is where scientific calculator facilitates our calculations.

Science is about Knowing. Engineering is about Doing. – Henry Petroski

Generally, in a basic calculator, you can perform basic arithmetic operations such as addition, subtraction, multiplication and division. But as you advance in professional learning, you need some special operations to calculate and solve the problems.

A Scientific calculator is a calculator that is enabled with important scientific, mathematical operations that help in solving even a complex problem, easily, and performs them with precision and accuracy.

- As per the historians and scientists, calculator dates back to 2000 B.C. They opine that the hand-operated Abacus in Egypt was the first human-made calculator.
- “Cal Tech” was the first handheld calculator which was designed by Jack Kilby at Texas Instruments in 1967. Interestingly, it printed the output on a paper, after performing addition, subtraction, multiplications and division.
- The first mechanical calculator “Calculating Clock” was invented by Willhelm Schickard.
- Calculators were originally gear-driven wheels; however, the recent ones are based on a chip or a microchip and contain some energy source.
- It was around 1642 when Blaise Pascal created a device that could perform arithmetic operations with two numbers, and mechanical calculators took their basic shape.
- Later in the 17th century, Europe made advancements in Mechanical calculators by incorporating the slide rule. It performed rapid multiplications by using logarithmic scales and was based on a sliding stick.
- World's first scientific calculator was developed by Hewlett Packard, which is a handheld calculator - the HP 35.

Mathematics is not about numbers, equations, computations or algorithms. It is about understanding.– William Paul Thurston

Scientific calculators eliminated the necessity to make a lookup into mathematical tables, such as trigonometric functions or logarithms. You can perform all these operations just using this single device.

Not only in mathematics, but a scientific calculator is used in physics, astronomy and chemistry to solve complex problems containing larger and scientific values.

Scientific calculators are very user-friendly. They include many useful features making it easier to translate a problem on a textbook page into calculator input.

Engineering students and professionals need this scientific calculator very often to solve the problems as normal calculator do not have these features and (or) do not give results with accuracy and precision.

- Powers and roots of a number.
- Factorial of a number.
- Fractions and Percentage calculations.
- Floating point arithmetic.
- Logarithmic functions, with two bases: base 10 and base e.
- Trigonometric functions such as sin, cos, tan.
- Exponential functions and roots of any value.
- Quick calculations with constants involving pi and e.

CalculatorHut’s scientific calculator is very user-friendly and easy to understand. All you need to do is to enter the equation or the values to be calculated and click the required symbol and then click ‘=’ symbol. You will get the required answer with exceptional accuracy.
