I have a question:
How can we write the set of real numbers odd and the set of real numbers
And thank you anyway
What I provided is the standard set notation for odds and evens as far as I know.
In terms of what you asked, why wouldnt you just write down Evens if you are going to use the word even,
The problem with that is you can define the odds and evens via set notation like I used, but you couldn't do that with what you said since you use the word even
but yes, I would have to say it would be correct to say n such that n is even, but it's redundant and doesn't tell you anything
