Find the additive inverse of the following :
`{:(a.,39,b.,-467),(c.,230,d.,-60):}`

Answer

To find the additive inverse of the given integers, we follow these steps:

### Step 1: Identify the numbers
We have the following numbers:
- 39
- -467
- 230
- -60

### Step 2: Determine the additive inverse
The additive inverse of a number is the number that, when added to the original number, results in zero.

- For a positive number, the additive inverse is negative.
- For a negative number, the additive inverse is positive.

### Step 3: Calculate the additive inverses
1. **For 39**:
- Since 39 is positive, its additive inverse is **-39**.

2. **For -467**:
- Since -467 is negative, its additive inverse is **467**.

3. **For 230**:
- Since 230 is positive, its additive inverse is **-230**.

4. **For -60**:
- Since -60 is negative, its additive inverse is **60**.

### Step 4: Write down the results
The additive inverses of the given numbers are:
- The additive inverse of 39 is **-39**.
- The additive inverse of -467 is **467**.
- The additive inverse of 230 is **-230**.
- The additive inverse of -60 is **60**.

### Final Answer:
- The additive inverses are: **-39, 467, -230, 60**.
