Thinking carefully ~
One day, Mary's father gave her 10 stalks of flowers and asked her to arrange all these flowers in 5 straight lines. Each line must have 4 stalks of flowers. How does Mary arrange these flowers ?
Oops ! This student was gave the wrong answer !
Aiya, this student also work out the wrong answer !
After discussion, still cannot get the answer. Then, they came and asked :" Teacher, 5 straight lines X 4 stalks of flowers = 20 stalks of flowers , not 10 stalks of flowers."
But teacher said there are 10 stalks of flowers only.
Oh, my god ! What should Mary done to get the answer ???
Let us see this student, she find the answer...
hahaha, this is the answer :
