4-404: MEV , Mev , meV , or variation , may refer to: MeV and meV are multiples and submultiples of the electron volt unit, ( eV ), referring to: Multiple (mathematics) In mathematics , a multiple is the product of any quantity and an integer . In other words, for the quantities a and b , it can be said that b is a multiple of a if b = na for some integer n , which
8-457: Is called the multiplier . If a is not zero , this is equivalent to saying that b / a {\displaystyle b/a} is an integer. When a and b are both integers, and b is a multiple of a , then a is called a divisor of b . One says also that a divides b . If a and b are not integers, mathematicians prefer generally to use integer multiple instead of multiple , for clarification. In fact, multiple
12-440: Is used for other kinds of product; for example, a polynomial p is a multiple of another polynomial q if there exists third polynomial r such that p = qr . 14, 49, −21 and 0 are multiples of 7, whereas 3 and −6 are not. This is because there are integers that 7 may be multiplied by to reach the values of 14, 49, 0 and −21, while there are no such integers for 3 and −6. Each of the products listed below, and in particular,
16-406: The products for 3 and −6, is the only way that the relevant number can be written as a product of 7 and another real number: In some texts , " a is a submultiple of b " has the meaning of " a being a unit fraction of b " ( a = b / n ) or, equivalently, " b being an integer multiple n of a " ( b = n a ). This terminology is also used with units of measurement (for example by
