Calculators make quick work of complicated arithmetic and make simple maths quick and accurate to improve productivity.

Calculators are a handy device used in a wide range of settings, including the education sector, administration, construction, engineering, and the medical profession.

• **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. Some of the additional buttons featured on a scientific calculator are inverses, PI, parentheses and more.

• **Type** - choose based on the tasks you do most regularly. However, if a scientific calculator is needed even occasionally, it's best to ensure you have one on hand.

• **Power** - most calculators are battery-powered, while others run on solar or mains power.

• **Memory** - for a scientific or graphing calculator, memory is an important aspect as these types can save a number of calculations for later use.

*Is a calculator a computer?*

Yes, calculators are classed as purpose-built computers specific to calculations. They feature programming for limited operations, however, so they don't have the ability to be upgraded in the same way a PC does.

*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.
