What's the difference between summation and total?

Summation


Definition:

  • (v. t.) The act of summing, or forming a sum, or total amount; also, an aggregate.

Example Sentences:

  • (1) Alphaxalone and endogenous steroid hormone metabolites inhibit the binding of [35S]-t-butyl bicyclophosphorothionate in some regions, enhance it in others and give biphasic concentration-dependence in others, apparently the result of algebraic summation of two effects involving regional-dependent enhancement or inhibition.

  • (20) It is wiser, in the light of results reporting individual differences in the existence and extent of the paradox, and its sensitivity to stimulus conditions, to side with Blake and Fox (1973) when they observed that it is not unreasonable to suppose that various stimulus conditions might yield varying amounts of summation or even inhibition.

Total


Definition:

  • (a.) Whole; not divided; entire; full; complete; absolute; as, a total departure from the evidence; a total loss.
  • (n.) The whole; the whole sum or amount; as, these sums added make the grand total of five millions.
