Examples

1、An expression that includes any of the inequality signs >, <, ≥ or ≤ is called an inequality.

用“>”, “<”, “≥”或“≤” 表示的关系式叫不等式。

2、In an inequality with unknowns, the value of the unknown, which can make the inequality true, is called the solution of the inequality. All the values of the unknown that satisfy the inequality are called the solution set of the inequality.

含有未知数的不等式中，能使不等式成立的未知数的值叫做不等式的解。不等式的解的全体叫做不等式的解集。

3、The process of finding the solution(s) of an inequality is called solving the inequality.

求不等式的解集的过程叫解不等式。

4、An inequality containing only one unknown of degree 1 is called a linear inequality in one variable.

只含有一个未知数且未知数的次数是1次的不等式叫做一元一次不等式。

5、Some linear inequalities with the same variable are called a system linear inequalities system in one variable.

由几个含有相同未知数的一次不等式组成的不等式组叫做一元一次不等式组。
