A teacher was trying hard to make her dumb student understand mathematics.
Teacher: Mathematics is not that difficult. Why can’t you understand it?
Student: I am sorry madam. Please guide me, I will concentrate and learn soon.
Teacher: Okay, tell me if you have 10 chocolates and someone takes 4 from you, how many you will be left with?
Student: 10. I love chocolates and I don’t like to share them with others.
Teacher: No, let’s say someone forcefully snatches 4 chocolates from you, how many you will be left with?
Student: 10 chocolates and a dead body.
