Work every question in your notebook.

1. Trace these lines. What do the boxes hold after line 3?

   q ← 38
   a ← q ÷ 5
   b ← q rem 5

   1. q = 38, a = 7.6, b = 3
   2. q = 38, a = 7, b = 7
   3. q = 3, a = 7, b = 3
   4. q = 38, a = 7, b = 3

2. What is shown?

   show 4 + 17 rem 5 * 3

   1. 6
   2. 13
   3. 3
   4. 10

3. A student traced these lines and wrote that m holds 21 at the end. The right answer is 15. What mistake did the student make?

   m ← 47
   m ← m rem 6
   m ← m * 3

   1. The student skipped line 2.
   2. On line 2, the student rounded 7.83 up to 8.
   3. On line 3, the student used the old value of m, 47.
   4. On line 2, the student used ÷ instead of rem.

4. x rem 6 is 0. Which of these could x be?

   1. 3
   2. 61
   3. 44
   4. 42

5. Trace these lines. Write exactly what is shown, one line for each show.

   s ← 200
   m ← s ÷ 60
   s ← s rem 60
   show m
   show s
