**determinant**is a linear function' of the elements of each column thereof, and also a linear function of the elements of each line thereof; moreover, that the**determinant**retains the same value, only its sign being altered, when any two columns are interchanged, or when any two lines are interchanged; more generally, when the columns are permuted in any manner, or when the lines are permuted in any manner, the**determinant**retains its original value, with the sign + or - according as the new arrangement (considered as derived from the primitive arrangement) is positive or negative according to the foregoing rule of signs.It at once follows that, if two columns are identical, or if two lines are identical, the value of the

**determinant**is = o.It may be added, that if the lines are converted into columns, and the columns into lines, in such a way as to leave the dexter diagonal unaltered, the value of the

**determinant**is unaltered; the**determinant**is in this case said to be transposed.By what precedes it appears that there exists a function of the n 2 elements, linear as regards the terms of each column (or say, for shortness, linear as to each column), and such that only the sign is altered when any two columns are interchanged; these properties completely determine the function, except as to a common factor which may multiply all the terms. If, to get rid of this arbitrary common factor, we assume that the product of the elements in the dexter diagonal has the coefficient + 1, we have a complete definition of the

**determinant**, and it is interesting to show how from these properties, assumed for the definition of the**determinant**, it at once appears that the**determinant**is a function serving for the solution of a system of linear equations.Observe that the properties show at once that if any column is = o (that is, if the elements in the column are each = o), then the

**determinant**is = o; and further, that if any two columns are identical, then the**determinant**is = o.Reverting to the system of linear equations written down at the beginning of this article, consider the

**determinant**I a,' b, I formed out of the elements of the original**determinant**, by selecting the lines and columns at pleasure, is termed a minor of the original**determinant**; and when the number of lines and columns, or order of the**determinant**, is n - I, then such**determinant**is called a first minor; the number of the first minors is = n 2, the first minors, in fact, corresponding to the several elements of the**determinant**- that is, the coefficient therein of any term whatever is the corresponding first minor.The first minors, each divided by the

**determinant**itself, form a system of elements inverse to the elements of the**determinant**.Laplace developed a theorem of Vandermonde for the expansion of a

**determinant**, and in 1773 Joseph Louis Lagrange, in his memoir on Pyramids, used determinants of the third order, and proved that the square of a**determinant**was also a**determinant**.To Gauss is due the establishment of the important theorem, that the product of two determinants both of the second and third orders is a

**determinant**when of uneven degree vanishes, for if we multiply each row by - I we multiply the**determinant**by (- I) n = -1, and the effect of this is otherwise merely to transpose the**determinant**so that it reads by rows as it formerly did by columns, an operation which we know leaves the**determinant**unaltered.Making the substitution in any symbolic product the only
