Are negative numbers always less than positive numbers? 
No!  negative numbers are the opposite of a positive number. That does not mean they are less than positive numbers.
Ex. Rewrite each sentence as a positive or negative number 
Shuaib walked 3 miles east -> +3
Shuaib walked 3 miles west -> -3 
Either way, Shuaib walked the same amount.  The negative or positive shows the direction
