addition

There was girl who did not know how to do addition and subtraction didn't even afford to learn it as the thought that its all about increasing and decreasing the numbers to play with them. Days passed and she was a big girl now. Her mother said that plz bring 10 apples and gave her 200. She was going the shop now.

Shopkeeper gave her 20 apples . 1 apple cost 5 rupees so total she had to gave were 50 rupees. but as she had a note of hundred ,she gave it. As shopkeeper was a little greedy he didn't gave her 50 rupees. When she came back the mother asked for balance. The girl said I don't have balance. Her mother asked the cost of apples . Girl answered and the mother got angry and shocked. her mother said u are mad you should get 50 rupees back. Her mother also answered that as you were not conscious about math u did very bad mistake and the girl relieved her mistake.
