Answer 1

Let's clarify what is being asked.

You have two lines representing expressions of addition:

- **Line 1**: 4 plus 6 (4 + 6)
- **Line 2**: 6 plus 4 (6 + 4)

In terms of dots, we can represent the numbers as follows:

**Line 1 (4 + 6)**:
- **4** can be represented as ●●●● (4 dots).
- **6** can be represented as ●●●●●●● (6 dots).
- The expression can be rewritten as:
●●●● plus ●●●●●●●

This totals to **10 dots**.

**Line 2 (6 + 4)**:
- **6** can again be represented as ●●●●●●● (6 dots).
- **4** can be represented as ●●●● (4 dots).
- The expression can be rewritten as:
●●●●●●● plus ●●●●

This also totals to **10 dots**.

### Summary:
Both Line 1 and Line 2 involve 10 dots representing the sums of 4 + 6 and 6 + 4, respectively.

So in the answer to your attempted question:

- Line 1 represents 4 plus 6 with a total of **10 dots**.
- Line 2 represents 6 plus 4 with a total of **10 dots**.

Despite the different order of summands, the total remains the same.
