What is the Table of 28?
The table of 28 is also known as the multiplication table of 28. It shows us the values that we obtain by multiplying 28 with natural numbers. The table of 28 can be written using two operations – multiplication and addition.
Table of 28 using multiplication
We can find the multiplication table of 28 by multiplying 28 with a natural number, that is, 28 x n, where n is a natural number.
So,
for n = 1, 28 x 1 = 28
for n = 2, 28 x 2 = 56 and so on.
The table can be extended to higher values of n as well.
Table of 28 by Repeated Addition Method
We can find the multiplication table of 28 through the repeated addition of 28 in the following way:
Similarly, we can add 28 more than 10 times to extend the table to higher values.

Solved Examples
Example 1: Using the table of 28, evaluate 6 times 28 plus 14.
Solution:
The value of 6 times 28 plus 14, is given as-
(6 × 28) + 14
= 168 + 14 [From times table of 28]
= 182 [Add]
Hence, 6 times 28 plus 14 is 182.
Example 2: Find the value of 28 times 7 by using the repeated addition method?
Solution:
For 28 times 7 by repeated addition method, we will add 28 seven times
28 + 28 + 28 + 28 + 28 + 28 + 28 = 196
Hence the value of 28 times 7 is 196.
Example 3: Max bought 5 boxes of cookies and each box has 28 cookies. What is the total number of cookies Max bought?
Solution:
Number of boxes = 5
Cookies in each box = 28
To find the total number of cookies Max bought we will multiply the number of boxes by the number of cookies in each box.
So, we have to find 28 times 5
28 × 5 = 140 [From times table of 28]
Therefore, Max bought a total of 140 cookies.
The mathematical operations like multiplication and addition are used to find the table of 28.
The multiples of the number 28 are those numbers that we get as a result of multiplying 28 by any natural number.
The times table of 28 shows the values that we get by multiplying 28 with natural numbers.
The value of 28 times 4 is 112.
If we observe the multiples of 28 we notice that the ones place digits of the multiples are even numbers. This is because 28 itself is an even number.
