How Do you write "A is the set of even whole numbers less than 12" in the notation builder?

    my problem is i don't know how to write it is it like this: A={x|x<...,x \[\in \] ...} (note that "...." means i don't know what to put in there)

    \[2\mathbb Z\]is the set of even numbers.

    \(x\) is more than or equal to \(0\) and less than or equal to \(12\).

    For example, you can write the set of first ten natural numbers as:\[\{x\in\mathbb N: x \le 10\}\]

    for example if you are asked to write set of all even numbers you can write it as A={ x:x=2n ;n \(\in\) N} N is set oof all natural numbers

    Nah, I'd just use\[A = \{x:x\in2\mathbb Z \}\]And BTW, @AravindG, it should be the set of integers :-)

    I wanted to make it clear ..in schools we are first taught in that fashion ,then we play with it :) @ParthKohli

    But even numbers belong to the set of integers, not only N.
