Tricks to Memorize the Table of 28

Memorizing the table of 28 can be rather tough. But there are some tricks that can make this process easier. For example, the multiples of 28 are all whole numbers or commonly known as integers. Also, 28 is the multiple of 7 and 4. Now seven is a prime number and 4 is the square of two. If we can write the table of 28, we can write it as,

28 x 1 = 28, 28 x 2 = 56, 28 x 3 = 84 etc. Also, the table of 8 can be written as, 

8 x 1 = 8, 8 x 2 = 16, 8 x 3 = 24 etc. Now, the last digits of the multiples of 8 are same as the last digits of the multiples of 28. 

Solved Example

Example 1: By taking the help of the table of 28, solve for 5 times 28.

Answer. To solve for this problem, first we should refer to the table of 28 and also to express the problem mathematically. 

We can write the problem as,

28 x 5

Now, if we refer to the table of 28, we get that 28 x 5 = 140

Thus, the result of five times 28 is 120.

Example 2: By the table of 28, find the value of three times twenty-eight.

Answer. To solve this problem first we should read the table of 28 and express the problem mathematically

To express the problem mathematically, we can write that,

28 x 3

Now if we refer to the table of 28, the value of 28 x 3 is equals to 84.

Thus, the value of three times 28 is 84.
