Alright lets see how good you are. Are there more odd numbers or odd and even numbers ?

>> No.9611068

>>9611050
No

>> No.9611165

more odds since all negative numbers are odd

>> No.9611166

>>9611050
define "more"

in the poset of subsets of the naturals ordered by subsets, the odd numbers are strictly below the naturals
but the odd numbers are also equicardinal with the naturals

All odd numbers have a negative equivalent
Almost all even numbers have a negative equivalent
0 and -0 are the same thing
Because 0 has no proper negative equivalent, there is one fewer even number than odd

There are infinitely many odd numbers and infinitely many even numbers. Infinity isn't a number you can graph.

No, they're not.
OP specified a series of odd numbers and a series of odd and even numbers.
A grade school student could tell you the series of odd and even numbers would be the larger infinite series. At any odd number in the first series, the second series would have nearly twice as many numbers at the same odd number.

For the set of all odd numbers to be aleph-0 it must be paired with the set of all even numbers.

his question was :
let a represent odd numbers;
let b represent even numbers;
let c = a+b;
now his question was :
"Are there more odd numbers or odd and even numbers?"
is a>c
the awser is : yeah we have more odd and even numbers.

Depends on what mathematics you’re analyzing. Nicomachus classified numbers into three categories ‘even and odd’ ‘odd and even’ and ‘even and even’. It’s just based on the factors of the numbers involved to create that number. In truth, specifically, number types really are more complicated than people give them credit for and the two types ‘even’ and ‘odd’ is far too simplistic.
