Your dear Aunt Sally wanted to check and see how you did on her homework assignment.  
Picture
  1. \(5 \div 5(1+4) \)
  2. \(5(1+4) \div 5 \times 5 \)
  3. \(5 \times 5\div(1+4) \)
  4. \( (5 \times 5) \div[5(1+4)] \)
  5. \(5(5 \div 5)(1+4) \)
  6. \(5 \times 5\div[5(1+4)] \)


Here are Aunt Sally's answers:
  1. \(5 \div 5(1+4)=5 \)
  2. \(5(1+4) \div 5 \times 5=25 \)
  3. \(5 \times 5\div(1+4)=5 \)
  4. \( (5 \times 5) \div[5(1+4)] =1\)
  5. \(5(5 \div 5)(1+4)=25 \)
  6. \(5 \times 5\div[5(1+4)]=1 \)
