    • Calculus (Math) A method of computation; any process of reasoning by the use of symbols; any branch of mathematics that may involve calculation.
    • Calculus (Med) Any solid concretion, formed in any part of the body, but most frequent in the organs that act as reservoirs, and in the passages connected with them; as, biliary calculi; urinary calculi, etc.

    • n calculus A small stone; a pebble.
    • n calculus In pathology, a general term for inorganic concretions of various kinds formed in various parts of the body. Those concretions formed in the gall-bladder are called biliary calculi, or gall-stones; those formed by a morbid deposition from the urine in the kidneys or bladder are called renal, cystic, or urinary calculi; those formed in the substance of the lungs are called pulmonary calculi; and those formed in the salivary glands or their ducts are called salivary calculi. There are also gouty concretions called arthritic calculi, and others called pancreatic calculi, lacrymal calculi, spermatic calculi, etc.
    • n calculus In mathematics, any highly systematic method of treating a large variety of problems by the use of some peculiar system of algebraic notation. By the calculus, without qualification, is generally understood the differential calculus, invented by Leibnitz (although Newton's method of fiuxions comes virtually to the same thing). In this method quantities are conceived as varying continuously, and when equations exist involving several quantities, these quantities will, in consequence of these equations, vary together, so that there will be equations between their rates of change, the differential or infinitely small increment of a variable being denoted by the letter d written before the symbol denoting the variable. The differential calculus treats of the values of ratios of these differentials, and of the fundamental formulas into which these ratios enter. The integral calculus treats of integration, or the summation of an infinite series of differentials; it is largely an inverted statement of a part of the doctrine of the differential calculus, but it also introduces imaginary quantities and leads up to the theory of functions.

They crow binomial theorem,
With views (it seems absurd to us)
On differential calculus.

to pay the piper with each breath, yet love
knows not of death nor calculus above
the simple sum of heart plus heart.
