In the world of smartphones and tablets, everyone wants to have a scientific calculator they can carry with them. But if you’re anything like me, you’ve tossed that $45 calculator and picked up a $5 one instead. This is because of one thing: scientific calculators are not simple tools. They have a number of functions that most people can’t even hope to comprehend.


A digital calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have completely replaced slide rules in traditional applications, and are widely used in both education and professional settings.

The first 11 sections describe how to use the calculator and how to perform different types of calculations. Section 12 contains a calculator reference guide that you can refer to as needed for some of the main key sequences. (Source: www.open.edu)


By definition, a scientific calculator is a calculator designed to help you calculate science, engineering, and mathematics problems. It has way more buttons than your standard calculator that just lets you do your four basic arithmetic operations of addition, subtraction, multiplication, and division.

If you're in the market for a new calculator and want to figure out the absolute best, our curated list can help you. We've looked through all the available options and found the device from Texas Instruments as number one for its range of functions and intuitive user interface. If you're looking for more basic or more complex types, we've picked alternatives for you as well. (Source:www.amazon.com))


had some features later identified with scientific calculator designs. The HP-9100 series was built entirely from discrete transistor logic with no integrated circuits, and was one of the first uses of the CORDIC algorithm for trigonometric computation in a personal computing device, as well as the first calculator based on reverse Polish notation (RPN) entry. HP became closely identified with RPN calculators from then on, and even today some of their high-end calculators (particularly the long-lived HP-12C financial calculator and the HP-48 series of graphing calculators) still offer RPN as their default input mode due to having garnered a very large following.

The course describes some of the main features of a scientific calculator and encourages you to use your calculator, both for everyday arithmetic and for more complicated calculations that use the function keys as well. Key sequences, which describe which keys to press, are included in all the activities, so you can try out the ideas straightaway. (Source:www.open.edu))
