英语翻译
The product of any set of complex numbers and the new symbols is called a monomial.For example 15,x,2x,5x2y3t and 3√2xy are monomoials.The sun of two monomials is called a binomial .A sum of three monomials is called a trinomial and ,in general ,a sum of one or more monomials is called a ploynomial.

任意一组复数及初始标符的相乘被称之为单项式；例如：15,x,2x,5x2y3t and 3√2xy皆为单项式；两个单项式相加称之为二项式；三个单项式相加称之为三项式；总之,一个以上的单项式相加,都称之为多项式.
再问： the new symbols是标号的意思啊 初始标符的相乘是什么啊
再答： symbols=符号、标量 例如：2、5、等等为“复数” 2y=2 × y “任意一组复数及初始标符相乘被称之为单项式” 多打了一个“的”字。
再问： The degree of a polynomial depend on the variable under consideration.For example 3x2y3is of degree two in x with coefficient 3y3and of degree three in y with coefficient 3x2.这一句话也可以顺便翻译一下吗
再答： 多项式的次数取决于预设的变量。
