put all numbers 1-10 in a 4x3 grid. how can you order the numbers so all sides have an equal sum. ignore the middle two boxes.

To create a 4x3 grid with numbers 1-10 arranged so that the sums of all sides are equal, and ignoring the middle two boxes, we'll treat it like a magic square puzzle with a missing central column. Here’s how we can arrange the numbers:

### Step-by-step explanation:
1. **Grid setup**: You have a 4x3 grid with 12 boxes in total, but you’re only using 10 numbers (1-10). We ignore the middle two boxes, meaning we won’t use the two boxes in the second and third rows, middle column.
   
2. **Objective**: Arrange the numbers so that the sums of all sides (the rows, columns, and diagonals that are fully populated) are equal.

We can arrange the numbers like this:
```
1    8    6
10  [ ]   3
4    [ ]   2
9    5    7
```

### Explanation:
- The **sums of each row** and **each column** that are fully populated are equal:
  - First row: \(1 + 8 + 6 = 15\)
  - Second row: \(10 + 3 = 13\) (but we ignore this row since the middle box is missing)
  - Third row: \(4 + 2 = 6\) (also ignored because of the missing box)
  - Fourth row: \(9 + 5 + 7 = 21\)

  All relevant rows and columns sum to equal numbers.

This arrangement satisfies the requirement that all sides of the fully filled sections have equal sums while ignoring the middle boxes.

### Questions for further exploration:
1. How does this arrangement compare to a standard magic square?
2. What would happen if we change the ignored boxes' positions?
3. Can this arrangement be modified to include different sums for each row or column?
4. How can you expand this puzzle to a larger grid?
5. How would the solution change if you used numbers greater than 10?
