# How to use *Odd-number* in a sentence

According to this view, it is necessary to assume that, in all unsaturated compounds, two, or some even number of affinities are disengaged; and also that all elements which combine with an even number of monad atoms cannot combine with an

**odd number**, and vice versa, - in other words, that the number of units of affinity active in the case of any given element must be always either an even or an**odd number**, and that it cannot be at one time an even and at another an**odd number**.Again, when tungsten hexachloride is converted into vapour it is decomposed into chlorine and a pentachloride, having a normal vapour density, but as in the majority of its compounds tungsten acts as a hexad, we apparently must regard its pentachloride as a compound in which an

**odd number**of free affinities are disengaged.The problem of finding the sum of r terms is aided by graphic representation, which shows that the terms may be taken in pairs, working from the outside to the middle; the two cases of an

**odd number**of terms and an even number of terms may be treated separately at first, and then combined by the ordinary method, viz.By similar methods, a circular plate may be made to exhibit nodal lines dividing the surface by diametral lines into four or a greater, but always even, number of sectors, an

**odd number**being incompatible with the general law of stationary waves that the parts of a body adjoining a nodal line on either side must always vibrate oppositely to each other.The formula shows that except for numbers of the form (3n 2 n) the number of partitions without repetitions into an

**odd number**of parts is equal to the number of partitions without repetitions into an even number of parts, whereas for the excepted numbers these numbers differ by unity.AdvertisementThe hair is sometimes worn plaited (choti), usually an

**odd number**of thin plaits made into one large one, falling down the back and fastened at the end with ribbons.Thus, in place of his general tri-quaternion we might deal with products of an

**odd number**of point-plane-scalars (of form, uq+wr) which are themselves point-plane-scalars; and products of an even number which are octonions; the quotient of two point-plane-scalars would be an octonion, of two octonions an octonion, of an octonion by a point-plane-scalar or the inverse a point-plane-scalar.For real figures we have the general theorem that imaginary intersections, &c., present themselves in conjugate pairs; hence, in particular, that a curve of an even order is met by a line in an even number (which may be = o) of points; a curve of an odd order in an

**odd number**of points, hence in one point at least; it will be seen further on that the theorem may be generalized in a remarkable manner.And we have then the theorem, two odd circuits intersect in an

**odd number**of points; an odd and an even circuit, or two even circuits, in an even number of points.Thus, it must be supposed that in nitric oxide, NO, an

**odd number**of affinities are disengaged, since a single atom of dyad oxygen is united with a single atom of nitrogen, which in all its compounds with other elements acts either as a triad or pentad.AdvertisementThe oxide NO 2 must be regarded as another instance of a compound in which an

**odd number**of affinities of one of the contained elements are disengaged, since it contains two atoms of dyad oxygen united with a single atom of triad or pentad nitrogen.Do you have an old set of tea cups or an

**odd number**that don't make a whole set?Pagodas usually have an

**odd number**of levels (often just one in smaller structures), and may be square, rectangular or octagonal in structure.Birdwell surf shorts come in even and

**odd number**sizes up to 37.When creating your centerpiece arrangement, keep in mind that an

**odd number**of elements generally is more pleasing to the eye than an even number.AdvertisementThe back row needs to have an

**odd number**of people.If the number you get is an

**odd number**(i.e. 35), round up to the next even number (for example, 36).If it is an

**odd number**then add an inch to make it even.
