Find integers that are 'one less than' and 'one more than' the given integers :
`{:(a.,0,b.,-11,c.,19,d.,-50),(e.,100,f.,-101,g.,99,h.,-1):}`

Answer

To solve the problem of finding integers that are 'one less than' and 'one more than' the given integers, we will follow these steps for each integer provided:

### Step-by-Step Solution:

1. **Create Two Columns**: We will create two columns, one for 'one more than' and another for 'one less than'.

2. **Evaluate Each Integer**:
- For each integer, we will calculate:
- One more than the integer (by adding 1).
- One less than the integer (by subtracting 1).

3. **List the Results**: We will write down the results in the respective columns.

### Detailed Calculation:

#### a. For 0:
- **One more than 0**:
\[ 0 + 1 = 1 \]
- **One less than 0**:
\[ 0 - 1 = -1 \]

#### b. For -11:
- **One more than -11**:
\[ -11 + 1 = -10 \]
- **One less than -11**:
\[ -11 - 1 = -12 \]

#### c. For 19:
- **One more than 19**:
\[ 19 + 1 = 20 \]
- **One less than 19**:
\[ 19 - 1 = 18 \]

#### d. For -50:
- **One more than -50**:
\[ -50 + 1 = -49 \]
- **One less than -50**:
\[ -50 - 1 = -51 \]

#### e. For 100:
- **One more than 100**:
\[ 100 + 1 = 101 \]
- **One less than 100**:
\[ 100 - 1 = 99 \]

#### f. For -101:
- **One more than -101**:
\[ -101 + 1 = -100 \]
- **One less than -101**:
\[ -101 - 1 = -102 \]

#### g. For 99:
- **One more than 99**:
\[ 99 + 1 = 100 \]
- **One less than 99**:
\[ 99 - 1 = 98 \]

#### h. For -1:
- **One more than -1**:
\[ -1 + 1 = 0 \]
- **One less than -1**:
\[ -1 - 1 = -2 \]

### Final Results:
Now, we can summarize the results in a table format:

| Integer | One More Than | One Less Than |
|---------|---------------|----------------|
| 0 | 1 | -1 |
| -11 | -10 | -12 |
| 19 | 20 | 18 |
| -50 | -49 | -51 |
| 100 | 101 | 99 |
| -101 | -100 | -102 |
| 99 | 100 | 98 |
| -1 | 0 | -2 |
