Times Table 30 as Addition
We know that multiplication can be expressed as form of repeated addition. We can get the next multiple of 30, by adding 30 in the previous multiple of 30. Similarly, we can add 30, n times to get its nth multiple. For Example, 30 × 5 can be written as 30 + 30+ 30 + 30 + 30. We can prove this as follows:
30 + 30 + 30 + 30 + 30 = 30 × 1 + 30 × 1 + 30 × 1 + 30 × 1 + 30 × 1
= 30(1 + 1+ 1 + 1+ 1) [using the distributive property of multiplication]
= 30(5)
= 150
30 + 30 + 30 + 30 + 30 = 150
Similarly, the table given below represents the table of 30 in addition form.
