Calculators are an integral part of math and science classes.

A calculator is a handheld device that performs arithmetic calculations for its user.

It can be as simple as an ancient abacus or as complex as a modern-day, digital scientific and graphing calculator.

Calculators are used in many areas such as in engineering, mathematics, and computer programming. They have uses in various educational levels,from high school to post-graduate studies, and for other purposes such as accounting and scientific research and development.

Calculators are also useful if you need to do lots of maths - they save time and effort because you just have to remember one sequence for getting answers rather than remembering lots of sequences or doing without calculators altogether.
