Properties Of Real Numbers Worksheet With Answers Pdf
Real numbers are the set of numbers that can be expressed as a decimal, fraction, or irrational number. These numbers are used in various mathematical operations, including addition, subtraction, multiplication, and division. Understanding the properties of real numbers is crucial for students to solve complex mathematical problems with ease. In this article, we will discuss the properties of real numbers worksheet with answers pdf, which is an excellent way for students to practice and enhance their mathematical skills.
What are Real Numbers?
Real numbers are the set of numbers that include all rational and irrational numbers. Rational numbers are the numbers that can be expressed as a fraction, while irrational numbers are the ones that cannot be expressed as a fraction. The real numbers can be represented on a number line, which can be used to perform various operations, such as addition, subtraction, multiplication, and division.
Properties of Real Numbers
There are several properties of real numbers that are essential for solving mathematical problems. These properties generally fall into four categories: addition, subtraction, multiplication, and division. Here are some of the most important properties of real numbers that students should know:
Addition Properties of Real Numbers
The addition properties of real numbers include commutative property, associative property, and identity property. Here's what each property means:
Commutative Property
The commutative property of addition states that changing the order of the addends does not change the sum. In other words, a + b = b + a.
Associative Property
The associative property of addition states that changing the grouping of the addends does not change the sum. In other words, (a + b) + c = a + (b + c).
Identity Property
The identity property of addition states that adding zero to any number does not change the number. In other words, a + 0 = a.
Subtraction Properties of Real Numbers
The subtraction properties of real numbers include the additive inverse and subtraction property. Here's what each property means:
Additive Inverse Property
The additive inverse property of subtraction states that adding the opposite of a number is equal to subtracting the number. In other words, a + (-a) = 0.
Subtraction Property
The subtraction property of real numbers states that subtracting a number is the same as adding its opposite. In other words, a - b = a + (-b).
Multiplication Properties of Real Numbers
The multiplication properties of real numbers include commutative property, associative property, and identity property. Here's what each property means:
Commutative Property
The commutative property of multiplication states that changing the order of the factors does not change the product. In other words, a x b = b x a.
Associative Property
The associative property of multiplication states that changing the grouping of the factors does not change the product. In other words, (a x b) x c = a x (b x c).
Identity Property
The identity property of multiplication states that multiplying any number by 1 does not change the number. In other words, a x 1 = a.
Division Properties of Real Numbers
The division properties of real numbers include the multiplicative inverse and division property. Here's what each property means:
Multiplicative Inverse Property
The multiplicative inverse property of division states that dividing a number by its reciprocal is equal to multiplying the number by 1. In other words, a x (1/a) = 1.
Division Property
The division property of real numbers states that dividing a number is the same as multiplying it by the reciprocal of the divisor. In other words, a/b = a x (1/b).
