Yeah, mathematically that's strange. The last result states that "`null` is equal or greater than zero". Then one of the comparisons above must be correct, but they are both falsy.
The reason is that an equality check `==` and comparisons `> < >= <=` work differently. Comparisons convert `null` to a number, hence treat it as `0`. That's why (1) `null >= 0` is true and (3) `null > 0` is false.

From the other hand, the equality check `==` for `undefined` and `null` works by the rule, without any conversions. They equal each other and don't equal anything else. That's why (2) `null == 0` is false.
