Syn: To compute; reckon; count; estimate; rate.
Usage: {To Calculate}, {Compute}. {Reckon}, {Count}. These
       words indicate the means by which we arrive at a given
       result in regard to quantity. We calculate with a view
       to obtain a certain point of knowledge; as, to
       calculate an eclipse. We compute by combining given
       numbers, in order to learn the grand result. We reckon
       and count in carrying out the details of a
       computation. These words are also used in a secondary
       and figurative sense. ``Calculate is rather a
       conjection from what is, as to what may be;
       computation is a rational estimate of what has been,
       from what is; reckoning is a conclusive conviction, a
       pleasing assurance that a thing will happen; counting
       indicates an expectation. We calculate on a gain; we
       compute any loss sustained, or the amount of any
       mischief done; we reckon on a promised pleasure; we
       count the hours and minutes until the time of
       enjoyment arrives'' --Crabb.
