Harry Numbers

﻿In chapter 21, The Unknown Room, Harry is looking for The Room of Requirement. I want you to look for the magic number in this chapter. The way to find this magic number is to count up the number of times Harry's name is said, multiply that by the number of times Malfoy's name is said. You aslo need to count the number of times Hermione's name is said, multiply that by the number of times Ron's name is said, add it to Harry and Malfoy's number and subtract Slughorn's number.

Here is the formula: Harry x Malfoy + Hermione x Ron - Slughorn = Magic number

*Remember there is a specific order to finding the answer to a problem when you are adding, subtracting, and multiplying!
