You can put this solution on YOUR website! All of the numbers are odd. Recall that
odd + odd = even
even + odd = odd
-------------------------------------------------------
So that means
odd+odd+odd
(odd+odd)+odd
(even) + odd
odd
Therefore,
odd+odd+odd = odd
-------------------------------------------------------
Since adding any 3 odd numbers will result in an odd number. It is impossible to get an even number result. So it is impossible to get the result of 30 using just odd numbers in the blanks.
