Answer 1

To analyze the information provided for Line 1 and Line 2, we can break down the expressions as follows:

### Line 1:
Expression: **2, plus, 4** (which can be written as **2 + 4**)

1. The "plus" is the addition operator.
2. The first number (2) can be represented with 2 dots: ●●
3. The second number (4) can be represented with 4 dots: ●●●●
4. Total dots representation for Line 1: 2 dots for the first number and 4 dots for the second number.

So, Line 1 can be represented using:
- Dots for 2: ●●
- Plus: plus
- Dots for 4: ●●●●

Total number of dots in Line 1 = 2 (for 2) + 4 (for 4) = **6 dots**.

### Line 2:
Expression: **4, plus, 2** (which can be written as **4 + 2**)

1. The "plus" is the addition operator.
2. The first number (4) can be represented with 4 dots: ●●●●
3. The second number (2) can be represented with 2 dots: ●●
4. Total dots representation for Line 2: 4 dots for the first number and 2 dots for the second number.

So, Line 2 can be represented using:
- Dots for 4: ●●●●
- Plus: plus
- Dots for 2: ●●

Total number of dots in Line 2 = 4 (for 4) + 2 (for 2) = **6 dots**.

### Final Answer:
- The expression was rewritten using the **plus** operator.
- Line 1 says **plus**, which could be represented using dots as ●● plus ●●●● for a total of **6 dots**.
- Line 2 says **plus**, which could be represented using dots as ●●●● plus ●● for a total of **6 dots**.

Thus, in summary:
- Line 1: 6 dots
- Line 2: 6 dots
