Answer 1

To determine at which step Jillian made a mistake while using integer tiles to add \( 7 + (-2) \), we first need to outline the correct steps for this operation:

1. Start with the positive integer (7): This would be represented by 7 positive tiles.
2. Introduce the negative integer (-2): This would mean removing 2 tiles (or adding 2 negative tiles).
3. Combine the remaining tiles: After removing 2 tiles from the initial 7, you would end up with 5 positive tiles.

Thus, the correct answer to \( 7 + (-2) \) is \( 5 \).

To identify where Jillian made a mistake, we would need to see her steps. Without knowing her specific steps, I can't identify precisely at which step she erred. If you provide her steps, I can help pinpoint the error.
