Most calculators with scientific abilities perform a minimum of 100 different functions. These functions include math performed on simple calculators as well as trigonometry, exponents, statistic equations, and algebra. Some calculators can perform over 500 functions, including the ability to calculate binary, decimal, octal, and hexadecimal numbers. It is even possible to enter formulas with letters into the calculator.
In order to calculate so many formulas and problems, scientific calculators need the space to do so. Most calculators include the ability to type one line of numbers of 8 to 10 digits. The long line allows for large, high number calculations. Some calculators have up to four lines of 8 to 10 numbers. Users can have rows of number calculations in order to see how the calculation would look if on paper. Lines also allow for more tricky formulas.
Graphing calculators are a type of scientific calculator that also shows graphs of the calculations on the screen. Users can create line graphs, bar charts, and even pie charts that help to visualize the math. Since graphs require ample space, most graphing calculators have several lines on the screen for other calculations.
While most scientific calculators are designed for science and engineering there are some that help with business. All printing calculators have a built-in printer with a calculator paper roll that prints out the calculations. They contain several financial functions including sales tax to make business sales easier. These calculators are useful for businesses and accountants that want instant access to printed information.
It might seem that these calculators do enough already but the above functions are just the beginning. Here are some other features found with many calculators:
