Pocket number cruncher
A calculator is an electronic device that performs mathematical operations—addition, subtraction, multiplication, division, and often more complex functions.
Before pocket calculators became ubiquitous in the 1970s, the word referred to a person who calculates: The bank employed several calculators.
Now it's almost exclusively the device: I need a calculator for this math class.
Calculator apps on phones have largely replaced physical ones for everyday use.
