Answer 1

To understand the problem with Line 1 and Line 2, let's break down the expressions in detail.

**Line 1:**
- 2, plus, 5 (which corresponds to the expression 2 + 5)
- The number 2 can be represented as ●●, which means 2 dots.
- The word "plus" is just written as plus and not represented by dots.
- The number 5 can be represented as ●●●●●, which means 5 dots.

Thus, Line 1 can be represented using dots as:
- ●● plus ●●●●●
For a total of:
- 2 (from the number 2) + 0 (from "plus") + 5 (from the number 5) = **7** dots.

**Line 2:**
- 5, plus, 2 (which corresponds to the expression 5 + 2)
- The number 5 can be represented as ●●●●●, which means 5 dots.
- The word "plus" is again just written as plus.
- The number 2 can be represented as ●●, which means 2 dots.

Thus, Line 2 can be represented using dots as:
- ●●●●● plus ●●
For a total of:
- 5 (from the number 5) + 0 (from "plus") + 2 (from the number 2) = **7** dots.

Answer Summary:
- The expression was rewritten using the **dots**.
- Line 1 says "plus," which could be represented using dots as ●● plus ●●●●●, for a total of **7** dots.
- Line 2 says "plus," which could be represented using dots as ●●●●● plus ●●, for a total of **7** dots.
