Calculator types

Basic calculators   -   This type will perform the basic mathematical functions for quick-time working out.

• **Graphing calculators **   -   These calculators are capable of calculating multiple, complex equations, and feature a large screen which allows for plotted graphs to be displayed. They are the next step from scientific calculators.

Printing calculators   -   These models are available with or without a display screen and will create a printed record of multiple equations on an integrated paper roll.

Scientific calculators   -   This type of calculator is capable of complex equations and features a range of function buttons beyond the basic addition, subtraction, multiplication, and division functions.

What is a '5-function' calculator?

This is a standard calculator with the basic five functions of power, addition, subtraction, multiplication, and division.

What's the difference between a scientific calculator and a graphing calculator?

While both of these types of calculators are capable of performing complicated arithmetic, including trigonometry, PI and more, a graphing calculator has the function of a scientific calculator and then some. It's typically equipped with more memory and features a hi-res screen suitable for displaying the graph function and coordinate plotting it's known for.
