Math is a universal language. Every mathematician knows this, and there have been studies that back up the idea that math is a useful tool that can be used across cultures.
You might not be able to speak every language, but you can do math in any language, validating that math is the same everywhere. Furthermore, from algebra to calculus, the principles and rules of math are always the same. No matter where you are, 2 plus 2 will always equal 4.
Thankfully, some math properties make the subject a little easier to understand. In this article, we'll look at some of the most important basic properties of math as they relate to real numbers.
What are the Properties of Math?
In mathematics, a property is a characteristic that always remains true. Number properties are at the core of mathematics and help us to understand and work with complex equations and problems. Certain properties will always hold true whether you're dealing with addition, multiplication, division or anything else.
And when you know a property exists, you can use it to your advantage. For instance, if you're trying to solve a complex equation, you can use properties to simplify it and make it easier to solve.
Why Knowing the Properties of Math is Important
Unlike some other areas of mathematics, the properties of math do not just apply to equations and problems but are fundamentally related to real numbers.
Real numbers refer to all natural, rational, whole, integers and negative numbers.
Understanding the properties of math can also help you develop a better understanding of mathematics as a whole.
Understanding Number Properties
Number properties are the set of rules that dictate how numbers behave when they are added, subtracted, multiplied or divided.
Numbers have four main properties: distributive, associative, commutative and identity property, and each governs how a mathematical operation is carried out.
Without further ado, let's look at some of the most important properties of mathematics.
1. The Commutative Property
The commutative property is one of the most fundamental properties of mathematics. The commutative property states that the order in which you add or multiply numbers doesn't matter.
In other words, a + b = b + a and a × b = b × a.
From the example, with commutative property, you can change the position of the real numbers, but this rearrangement will not affect the sum. Even if you change the position of two numbers, the sum will remain the same.
Hence, just like the additive commutative property expressed here:
5 + 2 = 7 and 2 + 5 = 7
Notice that the sum remained the same despite the rearrangement.
We can consider another example with the equation 3×4. If we use the commutative property, we can rearrange the equation to 4×3. If you follow the rule, multiplying the two numbers in a different grouping/order will give the same answer.
2. The Associative Property
The associative property states that the order in which you group numbers doesn't matter. The associative property derives its name from the word ‘associate’.
We can define associative property as the grouping of three or more numbers in different orders and still arriving at the same sum after the addition or multiplication of the numbers.
In other words, no matter how the numbers are grouped, you can get the same answer.
Here are some examples
1 + (2+3) = (1+3) + 2
5 × (3 × 4) = (4 × 5) × 3
Here is another example, consider the equation (5+3)+2. Using the associative property, we can rearrange the equation to 5+(3+2).
With the associative property, we can group the numbers in any order we like and still arrive at the same sum or product.
The Associative Property of Addition
The associative property of addition means that when adding three or more numbers, regardless of the way you order the numbers, the sum or outcome will remain the same.
2 + (3 + 6) = (2 + 3) + 6
a (b + c) = (a+ c) = b
The Associative Property of Multiplication
The associative property of multiplication states that regardless of how numbers are grouped or rearranged, the final answer or product will be the same after multiplying the numbers.
4 (2 × 3) = ( 3 × 4) = 2
y(x × z) = (y × x) = z
Hence, Associative Property of Addition: 3 + (4 + 5) = (3 + 4) + 5
Associative Property of Multiplication: 2 (3 × 4) = (2 × 3) 4
Though associative and commutative properties may seem similar, there is a difference between them. While the associative property deals with three or more numbers, the commutative property only has two.
Associative property: 4 (2 × 3) = ( 3 × 4) = 2
Commutative property: 5 + 2 = 7 and 2 + 5 = 7
3. The Distributive Property
The distributive property is another important property of mathematics, and it states that you can distribute a number across an addition or subtraction equation.
For example, consider the equation 3 (4 + 5).
Using the distributive property, we can distribute the number 3 across the addition equation to get 3 × 4 + 3 × 5.
The distributive property is also called the distributive property of multiplication over addition and subtraction because the operands outside the bracket can be distributed between the operands or numbers in the parentheses.
For instance, in equation 2(3-4), the number 2 will be distributed or used in multiplying both numbers in the bracket before subtraction is done.
Thus, 2 (3 - 4) = 2×3 - 2×4
The same principle also goes for the distributive property of multiplication over division. If you can understand and remember the distributive property, you'll be well on your way to mastering algebra.
4. The Identity Property
Identity property states that when you introduce identity elements to numbers, it does not change the value of the number. Rather the number remains the same.
Identity property elements are 0 for addition and subtraction and 1 for multiplication and division.
For instance, 5 + 0 = 5
3 × 1 = 3
Additive identity property
Additive identity property is when the number 0 is added to any number; the value of the number does not change.
For example, 2 + 0 = 2
0 + 4 = 4
Multiplicative identity property
The multiplicative identity element is 1. The multiplicative identity property states that when the number 1 is multiplied by any other number, it does not change the value of that number.
For example, 3 × 1 = 3
1 × 7 = 7
