Thanks so much for helping me fix my grades in math, but I need your help again. I thought my homework would be easy. But then my teacher gave me some sample problems, and I don't understand them. Could you help me figure it out, and then solve the last problem?

1 + 1 = 10
4 * 3 = 14
87 - 23 = 27
11 + 9 = 14
6 - 15 = 15
21 * 0 = ?

The answer to the last question is:

18!

We see the following pattern:

ONE PLUS ONE = 10 characters
FOUR TIMES THREE = 14 characters
EIGHTY SEVEN MINUS TWENTYTHREE = 27 characters
ELEVEN PLUS NINE = 14 characters
SIX MINUS FIFTEEN = 15 characters
TWENTYONE TIMES ZERO = 18 characters
