Roger,

Actually, the factor  n + 10*m represent the Celcius temperature in 
terms of the units integer n, and the tens integer m. For example, if 
the Celcius temperature were 16, then  n = 6 and m = 1. The 
Fahrenheit temperature would then be (m + 10*n) or  1 + 60 = 61. The 
reason for using n & m is so that the unknowns become the integers 
between 0 and 9.
