They had to reduce all of them?! Kate didn't mean to sound so UN-Ravenclaw, but she never looked forward to do any type of calculation. At least this was something new (to her) in Arithmancy. She had never thought of telephone numbers being affiliated with purchasing a house. She guessed that numbers were important no matter what the numbers were there for.

She copied down the three phone numbers and began her calculations.

7323 8299
7 + 3 + 2 + 3 + 8 + 2 + 9 + 9 = 43
4 + 3 = 7


456 1111
4 + 5 + 6 + 1 + 1 + 1 + 1 = 19
1 + 9 = 10
1 + 0 = 1


9250 7111
9 + 2 + 5 + 0 + 7 + 1 + 1 + 1 = 26
2 + 6 = 8

Kate underlined the Karmic Debts. There were two of them, she thought--19 and 10.
