The digits from 0 to 9 can be used to form all the numbers. The numeral system Represents a useful set of numbers, reflects the arithmetic and algebraic structure of a number, and Provides standard representation. The writing system for denoting numbers using digits or symbols in a logical manner is defined as a Number system. It is denoted by ‘P’.Ī Number system is a method of showing numbers by writing, which is a mathematical way of representing the numbers of a given set, by using the numbers or symbols in a mathematical manner. It can be written in decimals and have endless non-repeating digits after the decimal point. Irrational numbers: Irrational numbers are numbers that cannot be expressed in fractions or ratios of integers.It includes all the integers and can be expressed in terms of fractions or decimals. Rational numbers: Rational numbers are the numbers that can be expressed as the ratio of two integers.It can be expressed as a+bi where “a” and “b” are real numbers. Complex number: Complex numbers are a set of numbers that include imaginary numbers.It includes all the positive integers, negative integers, fractions, and decimal values. Real number: Real numbers are the set numbers that do not include any imaginary value.Decimal numbers: Any numeral value that consists of a decimal point is a decimal number.The set doesn’t include fractions and decimals. Integers: Integers are the set of numbers including all the positive counting numbers, zero as well as all negative counting numbers which count from negative infinity to positive infinity.The set of whole numbers is represented by ‘W’. Whole numbers do not include fractions or decimals. Whole numbers: Whole numbers are positive numbers including zero, which counts from 0 to infinity.The set of natural numbers can be represented as N = 1, 2, 3, 4, 5, 6, 7,… It is the numbers we generally use for counting. The set of natural numbers is represented by ‘N’. Natural numbers: Natural numbers are the positive numbers that count from 1 to infinity.There are different types of numbers categorized into sets by the number system. Some examples of numbers are integers, whole numbers, natural numbers, rational and irrational numbers, etc. It is represented by numerals as 2, 4, 7, etc. Numbers are the mathematical values or figures used for the purpose of measuring or calculating quantities. Numbers generally are also known as numerals are the mathematical values used for counting, measurements, labeling, and measuring fundamental quantities. The value of a number is determined by the digit, its place value in the number, and the base of the number system. Numbers are used in various arithmetic values applicable to carry out various arithmetic operations like addition, subtraction, multiplication, etc which are applicable in daily lives for the purpose of calculation. It is the unique way of representing of numbers in arithmetic and algebraic structure.
