Here is a math problem that will be fun to see the various answers given . Just give your answer , don't explain how you arrived at it , just your answer to see what most come up with .

10

14

10 and 14, both are correct.  14 is more correct.

You did not provide sufficient or complete algerbraic expressions on the final line, so both can be correct.

Hope you don't work on dam inspections here in Northern California.

there is only one answer, which is 10

the rule of math is that multiplication & division is done before addition & subtaction

[XH29N0G]

There is an accepted order of operations (PEMDAS) that gives 10 (ditto the post above).  14 would follow some other rule.  I do not see the 28 (please explain), but I suppose in base 9, it would be 11. I cannot figure out if there is some other answer that has escaped us all.

Sorry,  Did not see the please don't post how you got the answer until after I did this one and the next one.  (Guess you should also have reading test.)

14

I would like to see the explanation of how to get to 10 when 14 seems clearly (to me at least) the only possible logical answer...as a screwdriver is 1, pliers is three and a drill is two. Four screwdrivers (4x1=4) plus pliers (3) times drill (2) is clearly 14???

[XH29N0G]

I think the 10 comes from multiply first (3*2) then add 4 from the order of operations rule.   14 would be following another order of operations rule that I have not seen, but may be there.   I still cannot figure out the 28.

Please Excuse My Dear Aunt Sally   ( PEMDAS) , order of operations .

Really? Must be US thing!...over here if you wanted the multiplication done first....it would have to be first in the line from the left.......pretty obvious really imo.

PEMDAS is an acronym for the words Parenthesis Exponents Multiplication Division Addition Subtraction. For any expression, all exponents should be simplified first, followed by multiplication and division from left to right and finally addition and subtraction from left to right

O.K , since you've solved that one ........

[alfaitalia]

1.....unless you have some other shady maths rule over there!!!

[tan top]

 hmmm   ,  I've come up with 13 or 12  for the second one  !         not even sure 14 was right on the first one  now    , unless the first  answer should of been a hammer !!  thinking if a selection of four screwdrivers  ,  pliers & a drill don't work  , use a hammer      i'm going to wait for my bus    

[birdsandbees]

Since only the last line is solvable..  2

..and Alf, maybe check with your grade 3 teacher on the rules of math.

I see what I did.  I had the value of the drill as 4 vs 2.   

[XH29N0G]

20?  unless I cannot count and it is
5
5
2=2

I was wondering what the first one would be if the third line was a 0 e.g. the screw driver also equaled 2?  would it be 2^4+6 or 2*4+6??  The drills work as 2+2 or 2^2.

10


and 12 for the second ,Assuming you keep adding as you drop from one line to the next........what happens when you assume?
