A calculator is a device or program that helps you perform arithmetic and other mathematical operations. In daily life it can be a pocket calculator, a computer app, or a built-in function on a phone, used for adding, subtracting, multiplying, and dividing. More advanced models handle fractions, percentages, roots, and memory storage. In computing, a calculator can also be a software module that computes values within a larger program. Colloquially, a careful person who double-checks numbers might be jokingly called a human calculator. The word comes from calculate, with the suffix -or turning the verb into a noun for a tool or a person.
