What is Repeated Subtraction?

Repeated subtractivity is an approach of subtracting the equal variety of items from a larger group. It is likewise well-known as division.

If the same number is repetitively subtracted from another larger number until the remainder is zero or a number smaller sized than the number being subtracted, we have the right to compose that in the develop of department.

For example:

If tright here are 25 balls and also we form a team of 5 balls each.

*

Here, the number 5 has been consistently subtracted 5 times. We deserve to say that the number 5 has actually been subtracted 5 times from 25. So, we can create this subtraction as 25 ÷ 5 = 5.

Similarly, to settle a department problem with recurring subtraction, we repetitively group and subtract the same number aobtain and aobtain to discover the answer.

Here are a few examples of repeated subtraction.

There are 34 stars. How many kind of teams of 4 stars in each have the right to be formed?

*

In the offered photo we have the right to check out 34 stars. Now, utilizing repeated subtractivity, we can group them in smaller teams of 4 stars in each team. We can start to subtract 4 stars continuously until we are left with 0 or a number less than 4.

*

34 - 4 = 30 30 - 4 = 26 26 - 4 = 22 22 - 4 = 18 18 - 4 = 14 14 - 4 = 10 10 - 4 = 6 6 - 4 = 2

We gain 8 groups of 4 and also with 2 stars remaining.

This instance can be mathematically written as 34 ÷ 4. Wbelow 34 is the dividfinish. The divisor is the number of stars in each group, that is, 4. The number of times 4 is subtracted is the quotient. So, 8 is the quotient and also the leftover stars are the remainder. So, 2 is the remainder.

Because repetitive subtractivity is division, it have the right to be composed in 2 ways.

Example: Let’s say tright here are 18 items. These deserve to be created in 2 ways as presented.

18 ÷ 618 ÷ 3

*

*

When the divisor is 6, we make groups of 6.

We acquire, 3 teams of 6.

So, 18 ÷ 6 = 3

When the divisor is 3, we make teams of 3.

We obtain, 6 groups of 3.

So, 18 ÷ 3 = 6

Fun fact:

Repeated subtraction is favor jumping ago from the bigger number until you obtain a zero or a smaller number.
