Answer 1

To clarify the expressions given in Line 1 and Line 2:

1. **Line 1: 6 + 4**
- This expression represents the sum of 6 and 4.
- In terms of dots, we can represent it as:
- Six dots (●●●●●●) plus four dots (●●●●).
- So, you would count a total of 10 dots (6+4=10).

2. **Line 2: 4 + 6**
- This expression represents the sum of 4 and 6.
- In terms of dots, we can represent it as:
- Four dots (●●●●) plus six dots (●●●●●●).
- So, you would also count a total of 10 dots (4+6=10).

Both expressions result in the same total of 10 dots, demonstrating the commutative property of addition (i.e., 6 + 4 = 4 + 6).

In summary:
- Line 1 has a total of 10 dots (from 6 + 4).
- Line 2 also has a total of 10 dots (from 4 + 6).

Thus, both lines reflect the same total using dots.
