TIMS Task

  1. (4 + 3) × 2 + 1 = 15
  2. True
  3. 4 + 3 × (2 + 1) = 13
  4. (5 + 4 − 3) × 2 = 12
  5. True
  6. 5 + (4 − 3) × 2 = 7
  7. Possible response: First I thought about what number times 2 is equal to 12. Since that answer is 6, I tried to see how I could use the first three numbers to equal 6. I saw that if I added 5 + 4 = 9 and then subtracted 9 − 3 = 6, I could then multiply 6 × 2 = 12. I put the parentheses around the 5 + 4 − 3.

R. Order of Operations

Circle each number sentence that is true. If a sentence is not true, add parentheses to make it true.

  1. 4 + 3 × 2 + 1 = 15
  2. 4 + 3 × 2 + 1 = 11
  3. 4 + 3 × 2 + 1 = 13
  4. 5 + 4 − 3 × 2 = 12
  5. 5 + 4 − 3 × 2 = 3
  6. 5 + 4 − 3 × 2 = 7
  7. Explain how you solved Question D.
