2) the sum of q and r is t

E

How E

"the answer is E Just because one isnt sure that either these numbers are positive or negative integers and one should also consider decimal and non-decimal integers"-----> am i right or their is something else in this question which i dont know?

• t must be smaller than both q and r, if both q and r are negative
  t must be greater than both q and r, if both q and r are positive
  t must be between q and r, if both q and r are of opposite signs

• p = 1, q = 1, s = 1, t = 2 --> Greatest = t
  p = -1, q = 1, s = 0, t = 0 ---> Greatest = q
