What does compute mean?
Compute is a formal verb meaning to calculate or determine a numerical result, whether through mathematics, careful reasoning, or — most commonly today — a computer. It derives from the Latin computare, meaning to reckon or sum up, which also gave English words like computation and computer. In modern usage, computing is strongly associated with machines processing data at high speed, but the word applies equally to human arithmetic: an accountant may compute a tax bill just as an algorithm computes a weather forecast. It carries a slightly technical, precise connotation, appearing frequently in engineering, science, finance, and programming. Related derivatives include computable (capable of being calculated) and computational (relating to calculation by machine). Though everyday speakers more often say 'calculate' or 'work out,' compute remains the standard term whenever accuracy, method, or machinery is emphasized.
verbTo calculate or determine something mathematically, especially by means of a computer; to work out an answer from given data.
- To calculate or determine a value or result mathematically, typically using a computer.
- (dated/rare) As a noun: a calculated quantity or result.
"The software computes the interest automatically each month."
"Engineers computed the bridge's maximum load before construction began."
"It took her only seconds to compute the bill without a calculator."
Before computers existed, 'computers' were people — usually women — hired to compute by hand.

Etymology of compute
Compute comes from the Latin computare, formed from com- ('together') plus putare ('to reckon, think, prune'), meaning to count up or calculate. The word entered English in the early 17th century, initially referring to arithmetic reckoning done by hand. Its modern association with machines dates from the mid-20th century, when electronic computers took over the task the word described all along. It shares its root with related borrowings such as computation, impute, and putative.

How compute is actually used
Formal to neutral in register; common in scientific, mathematical, and technical contexts. Increasingly used loosely for any mental calculation ('let me compute the tip'), though 'calculate' is more idiomatic in everyday speech.
Easily confused with compute
A computer is the machine that performs calculations, whereas compute is the action those machines (or people) carry out.
