There are a selection of calculators available. Some are extremely specialized, some quite simple. You will find calculators that may only do simple arithmetic, and ones that may find a single point on a parabola. Prices increase with complexity, so determining the right calculator can cut costs and aggravation.
Basic calculators are used for simple functions. Generally, less than ten dollars, basic calculators add, subtract, multiply, and divide. Some include a simple memory function, larger display, large-sized keys or even a see-through design to use with overhead projectors. Basic calculators are for easy arithmetic. They are powered by either batteries or even a small solar cell.
Most printing calculators are designed for used in bookkeeping and accounting. They contain all of the keys of a basic calculator, with additional keys that enable for easily finding percent, subtotal, grand total, tax rate, and a number of other functions used when totaling large quantities. The printability allows the user to check on for common entry errors like transposed or skipped digits, use the printout as a receipt or never to print. Most also include a rounding function and way to choose the quantity of decimal places.
A top-of-the-line printing calculator may cost significantly more than $100, though they can be found for less. Printing calculators can be found as battery operated portable models, though most require usage of an electric outlet.
Scientific calculators are frequently used by students. They are accustomed to solve mathematical, physics or chemistry problems. They are also often approved for used in standardized tests. These calculators may include multifunction buttons for a smaller, full featured tool algebra calculator free They have the ability to calculate root values, with separate buttons for square, cube, and any root. They also have trigonometric, logarithmic and exponential function keys.
Most have a single line display, but some can be found by having an expanded display. Aimed primarily at students, these calculators may cost as little as $10. More expensive scientific calculators usually support more functions, provide larger memory, or allow problems to be keyed in just as they seem in a textbook.
Business and Financial Calculators
Financial and business calculators are designed to be utilized mainly in calculating business-related equations, for students studying business calculus, and for tracking or plotting financial information. Financial calculators can build amortization tables for loan payments, determine APR, estimate compound interest, total paid, interest paid and other functions of money over time.
Business calculators include more prominent placement of the very common functions utilized in business calculus or math. They often include advanced statistical models and analysis functions. More expensive models include larger memory, more cash flows, and more functions.
Graphing calculators are some of the very expensive calculators. Large memory capacity, programmability, a sizable screen and the graphing ability itself make graphing calculators different from other varieties. Graphing calculators are expected in many college level math and physics courses, as well as in certain business classes. They have the ability to perform the majority of the functions found in other specialized calculators, though hardly any have print capabilities. These calculators are designed to plot and graph functions, and simplify solving equations.
Apart from the large screen, there is much overlap involving the graphing, scientific and financial calculators. Users who prefer the more expensive screen or the ability to graph, but don’t require the advanced financial functions of a business calculator or have the ability to program one, may like the graphing calculator because of its flexibility.
