Fill in the Blanks: Identifying Integers and Other Mathematical Concepts

In mathematics, we often come across various sets of numbers that are used to represent different mathematical concepts. In this article, we will explore the given sets of numbers and identify which set consists of integers. We will also discuss the properties of integers and other mathematical concepts related to the given sets.

What are Integers?

Integers are whole numbers that can be either positive, negative, or zero. They are a subset of real numbers and are used to represent quantities that can be counted. Integers are denoted by the symbol ℤ (Z) and include numbers such as ..., -3, -2, -1, 0, 1, 2, 3, ...

Properties of Integers

Integers have several properties that make them useful in mathematics. Some of these properties include:

Closure: The sum or product of two integers is always an integer.
Associativity: The order in which we add or multiply integers does not change the result.
Commutativity: The order in which we add or multiply integers does not change the result.
Distributivity: The product of an integer and the sum of two integers is equal to the sum of the products of the integer and each of the two integers.

Identifying Integers in the Given Sets

Now that we have a good understanding of integers, let's examine the given sets of numbers and identify which set consists of integers.

Set 1: {0,1,2,3}

This set consists of four numbers: 0, 1, 2, and 3. All of these numbers are integers, as they are whole numbers that can be counted.

Set 2: {-4,-5,-8}

This set consists of three numbers: -4, -5, and -8. All of these numbers are integers, as they are whole numbers that can be counted.

Set 3: {π, √12, √15}

This set consists of three numbers: π, √12, and √15. None of these numbers are integers, as they are not whole numbers that can be counted. π is an irrational number, and √12 and √15 are irrational numbers as well.

Set 4: {1/2, 1/10, 1/14}

This set consists of three numbers: 1/2, 1/10, and 1/14. None of these numbers are integers, as they are fractions and not whole numbers that can be counted.

In conclusion, the set of numbers that consists of integers is Set 1: 0,1,2,3} and Set 2 {-4,-5,-8. These sets contain whole numbers that can be counted, making them integers. The other two sets, {π, √12, √15} and {1/2, 1/10, 1/14}, do not contain integers, as they consist of irrational numbers and fractions, respectively.

The final answer is:

Set 1: 0,1,2,3} and Set 2 {-4,-5,-8 are the sets of numbers that consist of integers.
