The Calculus of Operations, in the greatest extension of the phrase, may be regarded as that science which treats of bthe combinations of symbols of operation, conformably to certain given laws, and of the relations by which these symbols are connected with the subjects on which they operate.
As the principal object of the present work is to reduce and simplify the labours of the student, and as the great practical utility of the Calculus of Operations, at present, arises from its bearing upon the Differential and Integral Calculus, and the Calculus of Finite Differences, the symbols of operation employed in illustration, and the laws by which they are governed, and those belonging to the branches of analysis named, and are consequently bfamiliar to the reader” (A Treatise on the Calculus of Operations, p. 1).
Two symbols F and G are said to be commutative when, u being the subject on which they operate,
FG u = GF u
A symbol F is said to be distributive when, u and v being two distinct subjects,
F (u+v) = F u + F v
A symbol F is said to be iterative, or to follow the law of indices, when
Fm Fn u = Fm+n u = Fn Fm u
It is to be observed that this third formula is not to be regarded as a law of symbolic combination in the same sense as the first, nor as a law of symbolic operation in the same sense as the second. In fact, Fm u is rather to be regarded as a mere abbreviated notation for the result of the operation F performed m times successively upon u,
F F F ... u
than as equivalent to the result of any operation raised to the power m, performed on u.
The laws stated being the principal ones which occour in the practical employment of the Calculus of Operations, we shall for the present confine our attention to them. They may be called, respectively,
II. the Law of Distribution
III. the Law of Indices
We may at once observe, that whatever theorem is true for any one symbol which satisfies these laws is true for every symbol which satisfies them.
Now the symbols of numbers satisfy them; indeed all algebraical equations may be considered as having the same subject, unity, and the constants, as denoting sums of operations performed on unity. Again the symbols of differentiation satisfy those laws; for if u be a function of the two independent variables x and y, it is known that
DxDy u = DyDx u
that, if u be a function of x only,
Dx (u+v) = Dx u + Dx v
Dxm Dxn u = Dxm+n u
Hence we deduce the important consequence, that every theorem in Algebra, which depends on those laws, has an analogue in the Differential Calculus” (A Treatise on the Calculus of Operations, pp. 8-9).
