    Hi. In arithmetic box puzzle, do we have to use other mathematic functions like factorials. I am unable to do it otherwise. Also, could you point me to some similar puzzles.

      Hi Nitin,
      No other Mathematic Functions are required to use other than what's already given (Multiplication, Addition and Subtraction in order). If you are still facing trouble, drop me an email at swaroop.guggilam@gmail.com . I will guide you through some starting steps if necessary or solution :).

      I haven't created more of that kind yet but hope to do soon, but here are few more links if you need to practice these kinds of puzzles from other places:

      Hi
      The answers in the second and the third column in your puzzle is wrong. The second column is 43 where as the third column is nowhere near 12. Is there a mistake in the puzzle given?

      Hi Shyla ravishankar,

      Welcome to my blog. I hope you are enjoying solving the puzzles.
      To answer your question, as i have mentioned in the problem definition, you need to follow BODMAS rule. Which is nothing but (Division, then multiplication , then addition/subtraction in order).
      So now if you see 2nd Column it will be read as:
      4+4*6-5
      i) Now if you solve it as in order from left to right (which I believe you did) , you get 4+4 = 8, 8*6 = 48, 48-5 = 43.
      But this is wrong.
      ii) Correct Way: 4*6 = 24, 24+4-5 = 23

      Similarly now for 3rd column:
      7*6 = 42, 6*5 = 30 , 42-30 = 12.

      I hope I answered your question and now it's clear how you get that solution.
      Please feel free to ask, if you have any more questions.

      Regards,
      Swaroop
