is $5+7$ even or odd?

anonymous · Answer

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

anonymous · Answer

then you can be pretty sure that it is always even

goformit, I've been on this site way before you.

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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.

anonymous · Answer

it said the answer was A? as in odd plus odd is odd?
a miracle

anonymous · Answer

$5+7=13$ unless my arithmetic has failed me again

anonymous · Answer

Maybe "of" means multiplication. So, 5 * 7 = 35. And 35 is an odd.

Oh wait, I think I answer my question.

anonymous · Answer

But that doesn't explain the sum of it.

anonymous · Answer

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 · Answer

Oh. So you do think the book has a mistake?

anonymous · Answer

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