21 Times Table as Repeated Addition
As we know, Any multiplication can be obtained by adding the same number to itself up to the number of times of we want its product. Let’s see how this works:
Suppose we have to find 21 × 5:
Then, We can find by just adding 21 in itself,
⇒ (21 + 21 + 21 + 21 + 21) = 105.
Hence the answer is 105.
Similarly, the table given below represents the table of 21 in addition form.
