The Golden Trio and Luke had just finished Transfiguration and were heading to Maths when Hermione commented

"You are so good at Science Luke. But how good are you at maths." Hermione said curiously.

"I am ok at it." Luke said modestly. Hermione to be honest was jealous of Luke's mind and about how he was so much better than her at Science. They sat down at a table together when Professor Lupin started talking

"Good morning class. Today we are starting with multiplication and working our way to harder things as some of you haven't been taught maths by your parents/guardians. I will be sharing this class with Professor Potter as some of you already know because I get ill a lot of the time."

"Question 1) What is 25x2" Most of the class put their hands up aside from most Slytherins as they don't think that they should be taught muggle things. Luke and Hermione were the first ones to put their hands up.

"Mr Smith"

"50" Luke answered straight away.

"Ok Question 2) 225*2" Hermione and Luke were the only ones who put their hand up.

"Miss Granger"

"450 sir."

"Correct. I will teach you the basics at first. After the school has finished maybe you will know what 5,600 * 9000 would be" The professor said thinking that even he didn't know what it is without writing it out. Luke put his hand up.

"Yes Mr Smith"

"The answer would be 50,400,000" Lupin looked shocked "Hold on a second" He wrote the question out and worked it out. Then looked at him in amazement

"That...That is correct Mr Smith. 20 points to Gryffindor"

How in Merlins name did he know that. This Luke Smith is a prodigy, I think I will ask the other professors about him.Lupin thought to himself

Luke was heading to his next class before lunch when he got stopped by some older students

"Excuse me." Luke said trying to get past.

"Oh you think you are so smart. Don't you?" The blonde student taunted.

"No, I never said that. Please may I get past"

"No you cant " The oldest one said and punched him. Luke fell unconscious and was dragged into a cupboard with a silencing spell on it.
