1. Integers: These are positive or negative numbers without any fractional component. They include whole numbers and their negative counterparts, as well as zero.
2. Natural Numbers: Also known as counting numbers, these are the numbers used for counting. They include positive integers starting from 1 and do not include any negative numbers or zero.
3. Rational Numbers: Any number that can be expressed as a fraction of two integers, where the denominator is not zero, is a rational number. This includes integers, whole numbers, and fractions.
4. Irrational Numbers: These are decimals that do not end and do not have repeating numbers. They cannot be expressed as fractions or ratios of integers. Examples include π (pi) and √2 (square root of 2).
5. Whole Numbers: This includes all positive integers (natural numbers) and zero. Whole numbers do not include any negative numbers or fractional components.
1. Natural Numbers: These are the numbers used for counting. They include all positive whole numbers from 1 onwards (1, 2, 3, 4, 5, ...).
2. Whole Numbers: These are similar to natural numbers, but they also include zero. Whole numbers consist of all positive natural numbers (including zero) and their negative counterparts (-1, -2, -3, -4, -5, ..., 0, 1, 2, 3, 4, 5, ...).
3. Integers: These are the set of whole numbers (including zero) and their negative counterparts (-1, -2, -3, -4, -5, ...).
4. Rational Numbers: Any number that can be expressed as a fraction of two integers (numerator and denominator), where the denominator is not zero. Rational numbers can be positive, negative, or zero, and they may terminate (e.g., 1/2, 3/4) or repeat (e.g., 1/3, 0.666...).
5. Irrational Numbers: These are numbers that cannot be expressed as a fraction of two integers. They cannot be written as terminating or repeating decimals. Examples of irrational numbers include the square root of 2 (√2), pi (π), and e (the base of the natural logarithm).
Note: Positive numbers include all numbers greater than zero, including natural numbers, whole numbers, integers, rational numbers, and irrational numbers.
1. Rational Numbers: These are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. To find whether a number is rational or not, you can check if it can be written as a fraction. For example, the number 3/4 is rational because it can be expressed as a ratio of the integers 3 and 4. On the other hand, the square root of 2 (√2) is not rational because it cannot be expressed as a fraction of two integers.
2. Whole Numbers: These are positive numbers, including zero, that do not have a fractional component. To determine if a number is a whole number, you can check if it is a positive integer or zero. For example, the numbers 0, 1, 2, 3, and so on are all whole numbers. However, numbers like -1 or 2.5 are not whole numbers because they have a fractional component or are negative.
3. Natural Numbers: These are the numbers used for counting or the positive integers excluding zero. To identify natural numbers, you can check if a number is a positive integer. For instance, 1, 2, 3, 4, and so on are natural numbers, but 0 and negative numbers like -1 or -2 are not considered natural numbers.
4. Irrational Numbers: These are decimal numbers that neither terminate (end) nor repeat. To determine whether a decimal number is irrational, you can check if it goes on infinitely without repeating any pattern. For example, the decimal representation of π (pi) = 3.1415926535897932384626433832795... is an irrational number because it goes on indefinitely without any repetition.
5. Integers: These include both positive and negative whole numbers, along with zero. To identify integers, you can check if a number is a whole number or its negative counterpart. For instance, -3, -2, -1, 0, 1, 2, 3, and so on are all integers.
