   Okay you wise guys/gals,
   
   You think your so smart with the first one, how about this one?
   
   You have 80 potatoes. You take the potatoes and divide them by half then add 6, multiplied by 5. How many potatoes do you have?

      According to your answer there are 830 potatoe pieces but actually you have 80 whole potatoes. Therefore the correct answer is 80 whole potatoes.

   Divide them by half, half of 80 is 40
   
   80/40=2
   
   add 6
   
   =8
   
   multiply by 5
   
   =40
   
   or 2 plus 6 multiplied by 5=32, but you put a comma which would infer the order of operations above.

   If you divide them by half (i.e. cut them in two) you'd have 160 potato pieces. If you add 30 more potatoes, you'd have 160 potato pieces and 30 potatoes.

    I made it 830.
    Start again.
    80 potatoes. Half them (as we do, becaue a whole potato unless they are small takes too long to cook) makes 160. Add 6. OK That's 166. Then multiply by 5 = 830 (actually I thought it was 560 the first time - it's late OK my head isn't so good).
    But again, it could be a trick question.
    The line asked "divide them by half" which isn't necessarily halfing them.

             Right there are several ways the actual sum can be looked at.
             But  you only have 80 potatoes to start with.
             The rest of the question only mentioned sums, nothing to do with your 80 potatoes.
             So you still have 80 potatoes?

    Depending on your interpretation of 'divide', there are several answers.
    
    The original question:
    [You have 80 potatoes. You take the potatoes and divide them by half then add 6, multiplied by 5. How many potatoes do you have?]
    
    If you divide the 80 potatoes 'by' half, you'd have 40 potatoes.  If you divided the potatoes 'in' half, you'd have 160 potato halves, but still no more than 80 potatoes.  I'm assuming 40.
    
    Ok..I think the rest of the question after the 'divide them by half' is a deception. 
    
    The real answer is in fact be 40 potatoes.
    
    Ok. WaffleCheese quit waffling...is it in fact 40?

    830 huh?  Well yes, but only if you consider the original 80 potatoes were cut 'in half', and not 'by half' as you put it. At that point there would still be 80 potatoes.  Your phrasing is faulty if your intended answer was 830.  830 what?
    
    You also didn't specify whether to add 6 'potatoes', or just the number 6.
    
    I still think the final adding and multiplying are just window-dressing. 
    
    The last part of the question is the most telling:
    "How many potatoes do you have?"
    
    No..I'm sorry, the answer is stil 40 (or 80) potatoes.   So there.  Good night.

       The other problem is solved by the mathematical rule we used in school of BODMAS the order of calculations in an equation;

    Actually, this is a tricky question. I used to have a friend, a math teacher and he was always challenging my son with these kind of questions. By coincidence, he gave him this one and I remember the solution.  They're hoping that you do this:
    
    80/2 + 6 x 5.
    
    What you should actually do is this:
    
    80 divided by 1/2 + (6 x 5).
    
    80 divided by 1/2 is the same as 80 x 2 (by the invert-and-multiply rule), so 80 divided by half is actually 160.
    
    So now you have 160 + (6 x 5).
    
    The order of operations dictates that you multiply before you add. 6 x 5 is 30. 160 plus 30 is 190.
    
    The correct answer is 190. The answer most people would get is 230 (the result of 40 + 6 x 5).
