How can you get 14, with 5 ODD numbers? My daughter is in the 5th grade and this was one of their problems and I have racked my brain with different combinations and cannot come up with it.
This has to be a trick question. You cannot get
a result of 14 by adding five odd numbers, because
the sum of five odd numbers has to be odd.
Now, what is the trick exactly? Well it could be
- - Use five DIGITS instead of five numbers:
11 has two digits, so you can get 11 + 1 + 1 + 1 = 14.
- - Use some multiplications instead of additions:
(1 x 1) + 3 + 5 + 5 = 14.
- - Use a silly joke:
"All prime numbers are odd numbers.
Except 2, which is the only prime number that is even.
This peculiarity makes 2 a little odd. Therefore, 2 is
an odd number. So we can write 2 + 3 + 3 + 3 + 3 = 14".
Some caution must be exerted when giving an answer to
a trick question: Some teachers of the dogmatic type might think
that the answer they have in mind is witty, and all the
other ones are just silly. So I cannot point at any of these
as being the right one. It may be yet another trick answer
that the teacher is looking for.
I hope this helps,
