The sum of an odd number of odd number is: A: Always odd. B: Always even. C: Sometimes odd, sometimes even. I don't care for the answer, since it already told me. I just don't understand what the problem is saying.

is \(5+7\) even or odd?

5 and 7 are odd numbers, but the sum of it is an even number.

then you can be pretty sure that it is always even

you can "prove" it if you like, knowing that an odd number looks like \(2k+1\)

Also, satellite, it said that the answer is A.

Odd number and odd number always equal even. Odd numbers finish in either: \(\{1,3,5,7,9\}\) So if you look at \(\{1,3,5,7,9\}+\{1,3,5,7,9\}\) No matter which number you pick from either set. The two added together always are even.

\(5+7=13\) unless my arithmetic has failed me again

Maybe "of" means multiplication. So, 5 * 7 = 35. And 35 is an odd. Oh wait, I think I answer my question.
anonymous
  • anonymous
But that doesn't explain the sum of it.
anonymous
  • anonymous
lol of might me multiply if you are asked what is 2o% of 100 but not if you ask what is the sum of 5 and 7
anonymous
  • anonymous
Oh. So you do think the book has a mistake?

\(\{ODD\}_1*\{ODD\}_2=ODD\) \(\{ODD\}_1+\{ODD\}_2=EVEN\) As long as \((ODD_1)\wedge(ODD_2)\gt0\)
