Revise your work on the Self Check problem from the last lesson based on the following questions.
- How can you tell if Emma's and Chen's work (from the previous Self Check problem) is correct or incorrect?
- Can you find one problem that you know was done incorrectly?
- Can you find one problem in which the distributive property was used incorrectly?
- What do parentheses in a problem tell you?
- Can you explain why the work you identified as incorrect is not right?
