[<LL calculatus, pp. of calculare reckon <calculus pebble <calx lime; with ref. to the use of pebbles in counting] Synonyms: account, compute, consider, count, deem, enumerate, estimate, number, rate, reckon. Number is the generic term. To count is to number one by one. To calculate is to use more complicated processes, as multiplication, division, etc. Compute allows more of the element of probability, which is still more strongly expressed by estimate; as, to estimate the cost of a proposed building. To enumerate is to mention item by item; as to enumerate one's grievances. To rate is to estimate by comparison, as if the object were one of a series. We count upon a desired future; we do not count upon the undesired. As applied to the present we reckon or count a thing precious or worthless. Compare ESTEEM.
