Riddle:

• Calculate this expression:
  
  6 ÷ 2 × (1 + 2)
  
  Hint: The answer is NOT 1.

Answer:

• People often do:
  
  6 ÷ [2 × (1 + 2)]= 6 ÷ [2 × (3)] = 6 ÷ 6 = 1
  
  But the correct method is:
  
  — First, parentheses: (1 + 2) = 3
  
  — Then division and multiplication from left to right: 6 ÷ 2 = 3 and 3 × 3 = 9
  
  Correct answer: 9

Riddle:

• What is the result of this expression?
  
  8 ÷ 2 (2 + 2)
  
  Hint: The answer is NOT 1.

Answer:

• Many people think the entire denominator comes first, so they do:
  
  8 ÷ [2 × (2 + 2)] = 8 ÷ [2 × (4)]=8÷8=1
  
  But the correct order is:
  
  — First, solve parentheses: (2 + 2) = 4
  
  — Then division and multiplication have the same priority and are done left to right: 8 ÷ 2 = 4 and 4 × 4 = 16
  
  Correct answer: 16
