### Exercise 14.1 Solutions

1. Which of the following sentences are statements? Give reasons for your answer.

1. There are 35 days in a month.
2. Mathematics is difficult.
3. The sum of 5 and 7 is greater than 10.
4. The square of a number is an even number.
5. The sides of a quadrilateral have equal lengths.
7. The product of (–1) and 8 is 8.
8. The sum of all interior angles of a triangle is 180°.
9. Today is a windy day.
10. All real numbers are complex numbers.

1. This is not a statement. While it is a declarative sentence, it’s universally false since no month has 35 days according to the Gregorian calendar.
2. This is not a statement. This sentence is subjective and varies from person to person. What might be difficult for one might not be for another.
3. This is a statement. It is a declarative sentence that can be proven true. 5 + 7 = 12, which is indeed greater than 10.
4. This is not a statement. It’s not universally true or false because it depends on the number. For example, the square of 2 (an even number) is 4 (even), but the square of 3 (an odd number) is 9 (odd).
5. This is not a statement. This is true for some quadrilaterals like a square, but not for all, like a rectangle.
6. This is not a statement. It’s an imperative sentence (a command) and cannot be classified as true or false.
7. This is a statement, and it is false. The product of (-1) and 8 is -8.
8. This is a statement. It’s a factual, declarative sentence and is universally true for triangles.
9. This is not a statement in this context. It’s a declarative sentence but can’t be classified as universally true or false without additional context (such as the specific day and location).
10. This is a statement, and it is true. In mathematics, every real number is a complex number with an imaginary part equal to zero.

2. Give three examples of sentences which are not statements. Give reasons for the answers.

1) Close the door.

Reason: This sentence is a command, not a declarative sentence. Statements in mathematics are declarative sentences that are either true or false. A command or imperative sentence like this one does not express a fact or proposition that can be true or false.

2) Is it raining outside?

Reason: This is a question. Questions cannot be classified as statements because they do not declare anything to be true or false. Instead, they seek information or clarification and are not propositions with a truth value.

3) Beauty lies in the eyes of the beholder.

Reason: This sentence expresses a subjective opinion or perspective, not an objective fact. In mathematics, a statement should be something that can be clearly defined as true or false. Subjective statements that vary from person to person and depend on personal views or experiences do not qualify as mathematical statements.
