History for calculate
In Latin the word calculus meant “pebble.” Because the Romans used pebbles to do addition and subtraction on a counting board, the word became associated with computation, and the phrase ponere calculos, literally, “to place pebbles,” was used to mean “to carry out a computation.” Latin words coming from calculus include calculator, “person able to do arithmetic,” and calculare, “to reckon,” from which we get the word calculate.
