First:
14 - 6 = 8

Now, the number 14 has one tens and four ones, therefore it can be written as : 10+4

Now, rewriting the given expression:
14-6 = 10+4-6 = 10-2

The result of 10-2 is also 8.

For this case we have the following expression:

14 - 6
The difference of both numbers is:

14 - 6 = 8
We note that for number 14 we have:
tens place: 1
ones place: 4
Therefore, number 14 can be rewritten as:

14 = 10 + 4
Thus, the given expression can be rewritten by replacing values such as:

14 - 6 = (10 + 4) - 6
Then, for associative property we have:

(10 + 4) - 6 = 10 + (4 - 6) 10 + (4 - 6) = 10 + (-2) 10 + (-2) = 10 - 2 10 - 2 = 8
We observe that the difference is also 8.
Answer:
the difference

14 - 6 = 8
Rewriting:

(10 + 4) - 6 = 8
