bất đẳng thức

1. (mathematics) an inequality

• Similarly to a đẳng thức (“equality”), a bất đẳng thức is to be proven, which means the presence of signs such as <, ≤, >, ≥ must be determined as true under the given conditions of the variable(s). Compare with a bất phương trình (“inequation”) which is not to be proved, but to be solved.
