This article explains the properties of mathematical operations, their types, and their practical applications. We start with its fundamentals before we dig deeper into its properties.
What are the “Properties of Operations” in Mathematics?
Properties of Operations are fundamental mathematical concepts, and their domain forms the building blocks of more complex mathematical concepts. They manipulate and transform numbers in various ways, with the four basic mathematical operations, viz. addition, subtraction, multiplication, and division.
To simplify the different types of mathematical and logical formulas, mathematicians have defined properties of math operations into five different types. Each of these operations has properties that dictate how they solve math problems. It helps students determine the correct type to solve mathematical problems correctly.
What are the 5 Different Types of Properties of Operations?
The five properties of operations are commutative, associative, distributive, identity, and inverse elements. Using all these types of properties in math provides the correct solution, whether it’s simple arithmetic or complex algebra.
Let’s discuss the types and properties in detail for ease of understanding. Also, this knowledge will help you solve complex MyMathlab Answers to progress in your assignments.
This property states that changing the order of the operands in an addition or multiplication operation
does not affect the result. In simple terms, Y+Z and Z+Y are the same. Similarly, YxZ and ZxY are the
same. This property is used frequently in mathematics, especially algebraic expressions, to help simplify
equations and make them easier to solve.
Example: If we add 2 and 3, the result is 5. The commutative property of addition states that we can also add 3 and 2 and still get the same answer of 5. Similarly, if we multiply 4 and 5, the result is 20. Also, multiplying 5 and 4 will give us the same result of 20.
The associative property states that we can regroup numbers while applying the properties of operations multiplication or addition, and the result will remain the same. In other words, the grouping of the operands does not affect the outcome of the operation. The associative property states that we can add or multiply a series of numbers in any order, and the result will be the same. This property is often used in algebra to simplify expressions and equations. We also use it in everyday life, as when we group numbers to perform mental calculations.
Example: If we have to solve an equation like (5+2)+3, we can also regroup this expression as 5 + (2+3), and in both cases, the result will be 10. Similarly, for multiplication, (5×2)x3 and 5x(2×3) yield the same result.
This property deals with multiplying a number by a sum or difference of numbers. This way, we can distribute the multiplication to each term or number within the parentheses. In other words, we can multiply each number inside the parentheses with the multiplier and then add or subtract the results. In simple terms, the distributive property allows us to break up the multiplication of a number, the multiplier, with a sum or difference of numbers into smaller, more manageable parts.
Example: For the expression 7x(2+3), the distributive property of multiplication states that we can distribute the multiplication of 7 to both terms inside the parentheses. This results in (7×2) + 7×3, which simplifies to 14 + 21, which is 35. Similarly, if we have the expression 4x(3–2), we can multiply 4 by both terms inside the parentheses, resulting in (4×3) – (4×2), which simplifies to 12 – 8, which gives 4.
This property defines the identity element as a special number that leaves a number unchanged when added to or multiplied by it. In simple terms, the identity property tells us that there are special numbers (0 for addition and 1 for multiplication) that, when added to or multiplied by any number, respectively, leave the outcome unchanged when used in math properties of operations.
Example: For addition, the identity element is 0, which means that when we add 0 to any number, the result is that same number, and for multiplication, the identity element is 1, which means that when we multiply any number by 1, the result is that same number.
The inverse property of addition and multiplication states that specific numbers exist that result in the identity element when added to or multiplied by another number. In simple terms, for every number, there exists a special number (its negative, for addition, and its reciprocal, for multiplication) that undoes or reverses the effect of the operation.
Example: For addition, the inverse of any number is its negative, because adding both gives the identity element 0. For multiplication, the identity element is 1, and any number’s reciprocal, its inverse, when multiplied by the original number, gives us the identity element 1.
So these were all the properties in math operations, and by applying these properties correctly, we can, for example, rearrange mathematical expressions without changing their values. Also, it is essential to follow the rules governing how math properties of operations impact our everyday mathematical dealings.<>
