Yeah, mathematically that's strange. The last result states that "`null` is greater than or equal to 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 (3) `null >= 0` is true and (1) `null > 0` is false.
