Question 962328
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.
