The subtraction is not commutative, it means that n - 12 is not the same as 12 - n, except when n is 12. For example, suppose that we have a statement such as n - 12 = 12 - n. Can we find a value for n which will satisfy our statement?
n - 12 = 12 - n (add n and 12 to both sides)
n + n - 12 + 12 = 12 + 12 - n + n
2n = 24 (divide by 2 both sides)
n = 12
Check:
n - 12 = 12 - n
12 - 12 =? 12 - 12
0 = 0 True
But, for all other values of n, the statement is not true. Let's say that n = 20
Does 20 satisfies the statement? Check:
n - 12 = 12 - n
20 - 12 =? 12 - 20
8 = -8 False
Hence, we cannot write n - 12 as 12 - n for n ≠12.

Bill earns m dollars per month and Angelo earns n dollars per month How many dollars do both earn in 1 year?
Lack of information, if your trying to solve m and n. But otherwise... x = 12m + 12n | ...or... | x = a + b---- a = Bill's yearly income | b = Angelo's yearly income | x = Total of both incomes ---- a = 12m b = 12n

Which expression is equal to 12m 12n?
The expression 12m + 12n is equal to 12 times the sum of m and n. This expression cannot be simplified further unless there are like terms that can be combined. If m and n are like terms, then the expression can be further simplified by factoring out the common factor of 12 to get 12(m + n).
