A student made this mistake:
Mistake: Adding before multiplying (3x + 5 with x=4 → 3×9).
1. What did the student do wrong?
2. Fix it. Show the correct work.

1. Evaluate 3n when n = 7.
2. Write an expression for '8 more than m.'
Write your own word phrase for a classmate, then evaluate it for x = 2.
Show your work and explain your reasoning.
Keep separate from students.
