put the answers in the boxs that goes were it belongs: -3 + 5 = 2 , 3 + (-5) = -2 , -3 + (-5) = -8 , 3 + 5 =8

Answer 1

To determine which expressions belong to the correct models based on their mathematical operations, we can categorize them as follows:

1. **Adding two positive numbers**:
- **3 + 5 = 8**

2. **Adding a positive number and a negative number**:
- **3 + (-5) = -2**

3. **Adding two negative numbers**:
- **-3 + (-5) = -8**

4. **Adding a negative number and a positive number**:
- **-3 + 5 = 2**

Now, we can place the responses in the appropriate boxes based on the categories determined:

1. **Adding two positive numbers**:
- 3 + 5 = 8

2. **Adding a positive number and a negative number**:
- 3 + (-5) = -2

3. **Adding two negative numbers**:
- -3 + (-5) = -8

4. **Adding a negative number and a positive number**:
- -3 + 5 = 2

You just need to insert each expression into the appropriate category box in your interface.
