noun

1. (mathematics, uncountable) The act or process of calculating.

   As a check on these calculations we note that the total probability for 0, 1, 2, or 3 successes must be one since there are no other possibilities. 1962, Hugh D. Young, chapter 3, in Statistical Treatment of Experimental Data, page 53
   Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories. 2012-01, Michael Riordan, “Tackling Infinity”, in American Scientist, volume 100, number 1, archived from the original on 2013-04-30, page 86
