You had posted problems involving boolean algebra:From these numbers: 45 20 24 36 18 08
Which are odd, and which ones are even?
Not being a mathematician (just user), I am kind of suspicious about my own comprehension of definitions. I wish you had used some other term as opposed to "non-standard" (which casts a shadow of "standard"). I think my khan-fusion would have been reduced if you had used terms like "irrelevant personal definition".Of course. Suppose we say that a number is "even" if and only if it is divisible by 5, "odd" if it is not. That's certainly "non-standard". Or we could say a number is "even" if and only if the sum of its digits is divisible by 9, "odd" otherwise.
Surely you are not asking if there is a standard non-standard definition?
