### Division is a repeated form of which other mathematical operation?

Subtraction

Step by Step Explanation:
1. Division is a repeated form of subtraction.
2. To understand this, let us take two numbers: 18 and 6.
3. Let us say we have 18 balls in a bag which we wish to divide equally among 6 kids.
4. 18 divided by 6 is 3, which means each kid should get 3 balls.
5. Now, let us start distributing (dividing) the 18 balls among the 6 kids, one by one.
6. In the beginning, we have 18 balls. As, we give 3 balls to the first kid, we are left with 18 − 3 balls, i.e. 15 balls.
7. As we give 3 balls to the next kid, we are left with 15 − 3 balls, i.e. 12 balls.
8. In this way, when we finish giving the last 3 balls to the last kid, we are left with zero balls in the bag.
9. We can see that when we were dividing 18 balls equally among 6 kids, 3 balls were repeatedly subtracted from the number of balls in the bag until there were zero balls remaining in the bag.
10. Hence, it can be said that division is a repeated form of subtraction.
