Fill in the blanks.
`{:(" 1 0 0 0 0 0 0"),(ul(-" * * * * 1")),(ul(" * 7 0 4 2 *")):}`

Answer

To solve the problem of filling in the blanks, we will break down the steps systematically.

### Step-by-Step Solution:

1. **Write the equation**:
We start with the numbers provided in the question. The equation can be represented as:
\[ 1, 0, 0, 0, 0, 0, 0, 1 - 7, 0, 4, 2 \]

2. **Convert to a manageable format**:
This can be interpreted as:
\[ 10,000,000 - 7,042 \]

3. **Perform the subtraction**:
We need to subtract \(7,042\) from \(10,000,000\):
\[ 10,000,000 - 7,042 \]

4. **Break down the subtraction**:
Start from the rightmost digit:
- From \(0 - 2\), we need to borrow from the next column. So, we have:
- \(10 - 2 = 8\) (after borrowing)
- Now, we have \(0 - 4\), again we need to borrow:
- \(10 - 4 = 6\)
- Next, \(0 - 0 = 0\)
- Next, \(0 - 7\), we need to borrow again:
- \(10 - 7 = 3\)
- Finally, \(9 - 0 = 9\) (no borrowing needed)

5. **Combine the results**:
After performing the subtraction, we get:
\[ 9,992,958 \]

6. **Identify the star values**:
The stars represent the digits we calculated:
- The first star corresponds to \(7\) (from \(9 - 2\))
- The second star corresponds to \(0\) (from \(9 - 0\))
- The third star corresponds to \(4\) (from \(9 - 5\))
- The fourth star corresponds to \(2\) (from \(9 - 7\))

### Final Answer:
The filled in blanks are:
- First star: \(7\)
- Second star: \(0\)
- Third star: \(4\)
- Fourth star: \(2\)
