Positive numbers less than 4

Less than means we do not include 4.

But positive means greater than 0, so we have:

{1, 2, 3}

 

Update, this has been added to our shortcuts.

You can type any expression in the form, positive numbers less than x where x is any integer.

You can also type positive numbers greater than x where x is any integer.

Same with less than or equal to and greater than or equal to.
