Find the following :
`{:(a.,|101|,b.,|-9|),(c.,|0|,d.,|-1|):}`

Answer

To solve the problem, we need to find the absolute values (modulus) of the given integers. The modulus of a number is its distance from zero on the number line, which is always a non-negative value.

Let's break it down step by step:

1. **Find |101|**:
- The absolute value of 101 is simply 101 because it is already a positive number.
- **Solution**: |101| = 101

2. **Find |-9|**:
- The absolute value of -9 is 9. The modulus function converts negative numbers to their positive counterparts.
- **Solution**: |-9| = 9

3. **Find |0|**:
- The absolute value of 0 is 0. Zero is neither positive nor negative, so its modulus is 0.
- **Solution**: |0| = 0

4. **Find |-1|**:
- The absolute value of -1 is 1. Again, the modulus function converts negative numbers to their positive counterparts.
- **Solution**: |-1| = 1

Now, let's summarize the results:

- a = 101
- b = 9
- c = 0
- d = 1

### Final Answers:
- |101| = 101
- |-9| = 9
- |0| = 0
- |-1| = 1
