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. Base 10.
