单词 inequality
释义 inequality

The state of not being equal. If two numbers x and y are known not to be equal, but the direction of inequality is not known, this is written xy. Inequality of known direction may be strong or weak. Strong inequality means x is larger than y, written x > y, or x is smaller than y, written xy. Weak inequality means x is larger than or equal to y, written xy, or x is smaller than or equal to y, written xy. Where x and y denote vectors rather than numbers, the notation for inequalities is more complicated: a mathematics textbook needs to be consulted.
