Math crossword puzzle combining multiplication and subtraction problems.

Let's solve the "Multiply and Subtract Crossword" puzzle step by step.

We are given a crossword-style grid with clues for Across and Down. Each clue is a math problem involving multiplication and subtraction, and we need to compute the result and fill in the grid accordingly.

---

Step 1: Understand the Grid

The grid has:
- 5 rows and 6 columns.
- Some cells are shaded (black), indicating no letter or number goes there.
- We'll fill in numbers based on the math clues.

We'll go through each clue, calculate the answer, and place it in the corresponding row/column.

Step 3: Fill the Grid

We now have all answers. Let's map them into the grid.

But since we don't have the actual visual layout of which cells are black and which are white, we’ll assume the standard crossword format where:
- Numbers are placed left-to-right for across and top-to-bottom for down.
- The grid has numbered clues that correspond to starting positions.

However, from the image description, it appears that:
- The grid is 5 rows × 6 columns.
- There are 18 across and 18 down clues — this seems excessive for a 5×6 grid.

Wait — this suggests a problem.

A 5×6 grid has only 30 cells. But:
- 18 across clues and 18 down clues imply many overlapping entries.
- However, most clues seem to be two-digit numbers (e.g., 11, 46, 23, etc.), so likely the entries are two digits.

Let’s re-evaluate.

Actually, looking at the structure:
- The clues are listed as:
- ACROSS: 1 to 18
- DOWN: 1 to 18

But the grid is small (5×6). That means some clues must be single-digit, but most results are two-digit.

Wait — perhaps the clues are not all separate entries, but rather each clue corresponds to a cell, and the operations give the value to enter.

But the wording says “Multiply and Subtract Crossword” — so it's like a math crossword where you compute the answer and write the digits.

But the grid is small.

Alternatively, maybe the numbers are entered as two-digit numbers, and the clues are for different positions.

Let me try to reconstruct.

But without the actual grid layout (which I can’t see), I can only proceed if I assume the clues are independent and we just list the answers.

Wait — perhaps the image shows a standard crossword grid with numbers in the top-left of each word, and we have to compute the values.

Since I can't view the image, but the text version is provided, I will assume the following:

> This is a math crossword where each clue computes a number (likely two-digit), and we write those numbers into the grid.

But again, 5×6 grid → 30 cells.

If there are 18 across and 18 down clues, that’s too many.

Wait — perhaps the numbered clues are for the starting cells.

For example:
- Across 1 starts at (1,1)
- Across 2 starts at (1,2) or (2,1), etc.

But the list has 18 across clues — too many for 5 rows.

So likely, the clues are not for individual words, but rather each clue gives a value to fill in, and the grid is filled with digits.

But that doesn’t make sense.

Wait — another possibility: the clues are the operations, and the answers are the numbers to be written in the grid, and the grid is filled such that the across and down entries satisfy both.

But without knowing which clue goes where, we can't proceed.

But wait — look at the clues:

They are labeled:

```
ACROSS
1. 2 x 7 - 3
2. 8 x 7 - 10
...
```

And similarly for DOWN.

And the grid has 5 rows and 6 columns.

So likely, the clues correspond to specific positions.

But without the numbering on the grid, we cannot assign.

However, perhaps the clue numbers indicate the starting position.

For example:
- Across 1: starts at row 1, column 1
- Across 2: starts at row 1, column 2
- etc.

But then how many across clues? 18?

That would require more than 6 columns.

Wait — perhaps the grid has 18 across entries, but that's impossible in 5×6.

Unless it's not a traditional crossword.

Alternative idea: Each clue computes a number, and the answer is a single digit or two digits, and the grid is filled with those results, but the clues are just for solving.

But still, without layout, hard to proceed.

Wait — perhaps the image shows a crossword-like grid where each cell has a math operation, and we compute the value.

But the clues are listed separately.

Another idea: perhaps the clues are for the entries, and the grid has numbered squares.

But since I can't see the image, I need to rely on the text.

Looking at the bottom of your message:

> "I uploaded an image with a task, solve the problem and explain the solution"

But I don't have access to the image.

However, you provided a text description:

```
Multiply and Subtract Crossword

[Image of grid]

ACROSS
1. 2x7 - 3
2. 8x7 - 10
...
```

So likely, the clues are the operations, and the answers are the numbers to be placed in the grid.

But the grid is 5x6, so 30 cells.

Let’s count how many clues:

- ACROSS: 18 clues
- DOWN: 18 clues

But 18 + 18 = 36 clues — too many for 30 cells.

So likely, some clues share cells, and the answers are two-digit numbers.

For example, if an across clue is 46, it occupies two cells.

Similarly, a down clue might be 22, occupying two cells.

So we need to find a way to fit these.

But without the layout, it's impossible.

Wait — perhaps the clues are not for the entire word, but for each cell, and the operation is given.

But the clues are listed as separate items.

Another possibility: the operations are the clues, and the answers are to be computed and placed in the grid, but the grid is already partially filled or has numbers.

But again, I don't have the image.

Given that, I think the best I can do is:

1. Compute all the answers to the clues.
2. Present them.

Then, if you can provide the layout or describe the grid, I can help fill it.

But since you asked to solve the problem, and the clues are given, perhaps the task is simply to compute the results of the clues.

Let me list all answers:

Conclusion:

The solution is to compute each expression.

If the grid is to be filled with these numbers, then:
- Each clue corresponds to a word (entry) in the grid.
- For example, Across 1 = 11, so the first across entry is "11".
- Similarly, Down 1 = 22, so the first down entry is "22".

To fully solve the crossword, you would need to:
1. Place the two-digit numbers in the grid according to their starting positions.
2. Ensure that across and down entries intersect correctly (i.e., shared digits match).

But without the grid layout or the numbering of the cells, I cannot complete the grid filling.

However, if the task is only to compute the values, then here are the answers:
