Examples

the vectors x, y and z form a basis of the 3-dimensional space all members of which can be written as ax + by + cz → basis

x + y = 4 and x -- y = 2 are consistent → consistent

in ``y = f(x)'', ``y'' is the dependent variable → dependent variable

a circle x²+y²=r² has parametric equations x=r cos θ and y=r sin θ in terms of the parameters r and θ → parametric equations

the points (x, y) and (--x, --y) are symmetrical about the origin → symmetrical

mathematical equality is transitive, since if x = y and y = z then x = z → transitive

Let x be y.

假定x=y → be

In y² and xⁿ，2 and n are superscripts.

y 2 和x n 中，2和n为上标。 → superscript

6 is a coefficient in 6ab, x is a coefficient in x(y+z).

6 是 6ab 中的系数，x 是 x(y+z) 中的系数。 → coefficient

the advantage of x over y

x与y相比所具有的优势 → advantage
