To determine which expressions belong to the correct models based on their mathematical operations, we can categorize them as follows:
-
Adding two positive numbers:
- 3 + 5 = 8
-
Adding a positive number and a negative number:
- 3 + (-5) = -2
-
Adding two negative numbers:
- -3 + (-5) = -8
-
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:
-
Adding two positive numbers:
- 3 + 5 = 8
-
Adding a positive number and a negative number:
- 3 + (-5) = -2
-
Adding two negative numbers:
- -3 + (-5) = -8
-
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.
