Be good at learning

Analysis;

"Good" is larger than "Xue" 1, and "Xue" needs to borrow 1 when subtracting "Sheng", so "Sheng" does not need to borrow when subtracting "Good". And life-beauty = learning.

Life is the biggest, good is the second, and learning is-1. It can be seen that if life is at least 9, goodness =5 and learning =4.
