Even Numbers 0 to 20
Even numbers are a fundamental concept in mathematics, and they are integers divisible by 2 without remainder. Even numbers play a significant role in organizing data, architecture, pairing, and grouping items equally. In this topic, we will learn about even numbers between 0 and 20.
Even Numbers 0 to 20
Even numbers are the numbers that can be divided by 2 evenly without remainder.
All even numbers are multiples of 2. The last digit of even numbers always ends with 0, 2, 4, 6, or 8.
There are a total of 11 even numbers ranging from 0 to 20. The even number follows a simple formula of 2n, where n is an integer.
Even Numbers 0 to 20 Chart
Learning about even numbers can be made easier with a visual aid that helps children grasp the concept more effectively.
A chart allows them to recognize the sequence of even numbers more clearly. Here’s a list of even numbers from 0 to 20:
List of Even Numbers 0 to 20
Even numbers are expressed in the form of ‘n = 2k’. Here, ‘k’ is an integer, and ‘n’ is the number.
These numbers are divisible by 2, and the remainder equals zero.
Now, let us list the even numbers from 0 to 20.
The even numbers from 0 to 20 are as follows: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20. There are a total of 11 even numbers.
Sum of Even Numbers 0 to 20
To find the sum of even numbers, the formula is - S = n(n+1), where ‘n’ is the count of even numbers, and ‘S’ is the sum.
There are a total of 11 even numbers, so ‘n’ = 10 (as we consider the largest integer n that satisfies 2n <= 20). Now we can substitute the value of ‘n’. S = 10(10 + 1) S = 10 * 11 = 110
Therefore, 110 is the sum of all even numbers from 0 to 20. If we add an even number to an even number, the answer will always be an even number.
Even numbers are multiples of 2. The sum of two multiples of 2 is also another multiple of 2, therefore, it is always an even number. For example, 8 + 12 = 20.
Subtraction of Even Numbers 0 to 20
Subtraction of even numbers involves subtracting each even number from the next.
Each even number is uniformly spaced by 2. If we subtract two even numbers, it gives an even number as the result. For example, 16 - 6 = 10 18 - 2 = 16 20 - 12 = 8
Even Numbers 0 to 20 Examples
Problem 1
Find the sum of even numbers between 6 and 16.
60 is the sum of even numbers between 6 and 16.
Explanation
As we know, 6, 8, 10, 12, 14, and 16 are the even numbers between 6 and 16.
Next, we need to calculate the sum of these numbers. 6 + 8 + 10 + 12 + 14 + 16 = 66
The sum of even numbers between 6 and 16 is 66.
Problem 2
Lily has 10 apples. She wants to divide them equally between her 2 baskets. How many apples will each basket get?
Each basket gets 5 apples.
Explanation
There are 10 apples with Lily, and it is an even number.
So she has to divide equally between her 2 baskets, making it — 10 / 2 = 5, therefore, each basket gets 5 apples.
Problem 3
In a classroom, there are 20 chairs. Each chair is labeled with a number. All the even-numbered chairs are reserved for students. How many even-numbered chairs are there?
10 chairs.
Explanation
To find the even-numbered chairs in the classroom, we divide the total number of chairs by 2 because only the even-numbered chairs are reserved for students. 20 / 2 = 10 So, 10 chairs are reserved for students in the classroom.
Problem 4
A farmer has 8 ducks, 12 goats, and 4 dogs. Each pair of legs makes an even number. How many legs do all the animals have?
72 legs in total.
Explanation
First, we have to calculate the total number of legs for each type of animal: Ducks have 2 legs, and there are 8 ducks, therefore: 8 * 2 = 16 Goats have 4 legs, and there are 12 goats, therefore: 12 * 4 = 48 Dogs have 4 legs, and there are 4 dogs, therefore: 4 * 4 = 16 Therefore, the total number of legs all the animals have is 16 + 48 + 16 = 80. The animals have 80 legs in total.
Problem 5
There are 18 people at a party. If the people are paired into sets of 2, how many pairs are there?
9 pairs.
Explanation
Pairing into sets of 2 means dividing the total number of people by 2.
We need to calculate it as: 18 / 2 = 9. If the people are paired into sets of 2, there are a total of 9 pairs.

Important Glossaries for Even Numbers 0 to 20
- Even number: Even numbers are the numbers that can be divided by 2 without leaving any remainder. It has a formula of 2n, where n is an integer. The last digit of even numbers always ends in 0, 2, 4, 6, or 8. For example, 0, 8, and 20 are some even numbers.
- Multiple: A number that is a product of multiplying a number by an integer. For instance, 2, 4, 6, 8, etc., are a few multiples of 2. These numbers are the result of multiplying 2 by other integers.
- Remainder: For even numbers, while divided by 2, the remainder is always zero. If we divide a number by another, the leftover value is known as the remainder.
- Division: The process of calculating the number of times one number is contained within another. For example, dividing 20 by 2 results in 10.
- Integer: A whole number that can be positive, negative, or zero, but not a fraction. Examples include -3, 0, 4, and 20.
