Below we have provided some of the important points to remember for NCERT Class 11 Maths Chapter 14 to ace your exams:

**1**. **Statement (Proposition) and Types of Statement:** A sentence is called a mathematically acceptable statement or simply a statement if it is either true or false but not both.

(i) **Declarative**:

Any statement which is either true or false but not both is called as declarative sentence.

(ii) **Imperative**:

Any imperative sentence such as command or a request cannot be a statement.
