  3) [(2+3)^3-4(5)]+7
  My way of solving:
  [(5)^3-4(5)]+7
  [123-4(5)]+7
  [123-20]+7
  [103]+7
  
  4) [25/ (2^3-3)]*2
  My way of solving:
  [25/(8-3)]*2
  [25/5]*2
  [5]*2
  
  Thanks for showing your work. It helps us to know where you are having trouble.
  #3. [(2+3)^3-4(5)]+7
  My way of solving:
  [(5)^3-4(5)]+7 You are ok to here.
  [123-4(5)]+7 5*3 125 not 123.
  [123-20]+7
  [103]+7 a second mistake here. 103 + 7 = 110
  My answer: 109 the correct answer is 112.
  
  #4. [25/ (2^3-3)]*2
  My way of solving:
  [25/(8-3)]*2
  [25/5]*2
  [5]*2 You are ok to here. 5^2 = 25 and not 10.
