1. **State the problem:** We need to find the sum of the credits in the given list. 2. **Formula used:** To find the sum of a list of numbers, we use the formula: $$\text{Sum} = a_1 + a_2 + a_3 + \cdots + a_n$$ where $a_1, a_2, \ldots, a_n$ are the credits in the list. 3. **Important rule:** Addition is commutative and associative, so the order of adding numbers does not affect the sum. 4. **Intermediate work:** Add each credit one by one, keeping track of the running total. 5. **Final answer:** The sum of the credits is the total obtained after adding all the numbers in the list.
