FAQs

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.
