#-34, -7, -6, 5, \abs{19}#

Explanation:

The 'greater' the value is for a negative number, the smaller it is:
#-28\lt-15#

The opposite of a number would be the negative version of it:

  • #-16# opposite #\rArr-(-16)=(-1\cdot-1)(16)=16#
  • #53# opposite #rArr-(53)=-1\cdot53=-53#

The absolute value of a number is always positive as it refers to distance from #0# on the number line (and distance is generally measured in positive terms):
#\abs{-82}=82#
