Table of 21 is the 21 times table that includes the multiples of 21. The multiples of 21 can be produced by multiplying 21 with each of the natural numbers starting from 1.
In schools, from the very primary classes, we start learning about Maths tables. These maths tables basically give the values of the repeated addition of a number. In the same way, the maths table of 21, gives the repeated addition of the number 21.
For example, 3 rows of 21 boys each gives the sum of 21 + 21 + 21 = 63. Therefore, the total number of boys is 63. Or we can also write it as, 3 x 21 = 63, where 3 is the number of rows and 21 is the number of boys standing in each row.

- Unit place digit of the multiple of 21 is the same as the whole number that is multiplied to it. For example, 21 x 3 = 63.
- The pattern of the table of 21 is such that at the unit place, the digits are consecutive (when we proceed with its multiples). 21, 42, 63, 84, 105, and so on
Q.1: What is the value of 21 times 3 added to 21 times 5?
Solution: 21 times 3 = 21 x 3 = 63
21 times 5 = 21 x 5 = 105
Sum = 63 + 105 = 168
Q.2: Evaluate: (21 x 10) – (21 x 6)
Solution: 21 x 10 – 21 x 6
= 210 – 126
