How do you convert the expression 168 + 48n into a difference?

1. Identify the terms in the expression \(168 + 48n\). Here, though not directly visible, the operation between the terms can be expressed using subtraction for finding a difference.
2. We observe that \(168 + 48n\) can be rewritten by simply acknowledging that adding a positive number is equivalent to subtracting a negative, i.e., \(168 + 48n = 48n - (-168)\) based on the property that \(a + b\) is equivalent to \(b - (-a)\) since subtracting a negative is the same as adding.
3. Thus, convert the addition to subtraction in the form of difference as \(48n - (-168)\).

Answer: 48n - (-168)
