Understanding the multiples of 20 helps solve mathematical problems and boosts our multiplication and division skills. When working with multiples of 20, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.

Sum of first 5 Multiples of 20:


20, 40, 60, 80, and 100 are the first five multiples of 20. When multiplying 20 from 1 to 5, we get these numbers as the products.  
So, the sum of these multiples is:


20 + 40 + 60 + 80 + 100 = 300


When we add the first 5 multiples of 20, the answer will be 300.

Subtraction of first 5 Multiples of 20:


While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 20, 40, 60, 80, and 100 are the first five multiples of 20. So, let us calculate it as given below:


20 - 40 = -20
-20 - 60 = -80
-80 - 80 = -160
-160 - 100 = -260


Hence, the result of subtracting the first 5 multiples of 20 is -260.

Average of first 5 Multiples of 20:


To calculate the average, we need to identify the sum of the first 5 multiples of 20, and then divide it by the count, i.e., 5. Because there are 5 multiples presented in the calculation. Averaging helps us to understand the concepts of central tendencies and other values. We know the sum of the first 5 multiples of 20 is 300.


20 + 40 + 60 + 80 + 100 = 300


Next, divide the sum by 5:


300 ÷ 5 = 60


60 is the average of the first 5 multiples of 20.

Product of First 5 Multiples of 20:


The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 20 include: 20, 40, 60, 80, and 100. Now, the product of these numbers is:


20 × 40 × 60 × 80 × 100 = 38,400,000

The product of the first 5 multiples of 20 is 38,400,000.

Division of First 5 Multiples of 20:

While we perform division, we get to know how many times 20 can fit into each of the given multiples. 20, 40, 60, 80, and 100 are the first 5 multiples of 20.


20 ÷ 20 = 1
40 ÷ 20 = 2
60 ÷ 20 = 3
80 ÷ 20 = 4
100 ÷ 20 = 5    

The results of dividing the first 5 multiples of 20 are: 1, 2, 3, 4, and 5.
