Question

why should we count the change after buying something​

Answer 1

Answer:

Explanation:So we can confirm whether the shopkeeper did a mistake in counting or not and to save money.

Answer 2

We should always count the change after buying something due to the following reasons:

1) in case the change is either less or more.

2) in case the shopkeeper intentionally provided less change.

Counting change will be helpful in checking the amount you spent while buying and the amount that you are left with and hence leading to keeping a check on your spending.
