2. Fill in the blanks with or sign.
(a) (– 3) + (– 6) ______ (– 3) – (– 6)
(b) (– 21) – (– 10) _____ (– 31) + (– 11)
(c) 45 – (– 11) ______ 57 + (– 4)
(d) (– 25) – (– 42) _____ (– 42) – (– 25)
(a) (– 3) + (– 6) ______ (– 3) – (– 6)
LHS - 3 - 6 = -9
RHS - 3 + 6 = +3
Hence LHS < RHS
(b) (– 21) – (– 10) _____ (– 31) + (– 11)
LHS - 21 +10 = -11
RHS -31 - 11 = -42
Hence LHS > RHS
(c) 45 – (– 11) ______ 57 + (– 4)
LHS 45 + 11 = 66
RHS 57 - 4 =53
Hence LHS > RHS
(d) (– 25) – (– 42) _____ (– 42) – (– 25)
LHS - 25 + 42 = 17
RHS -42 + 25 = -17
Hence LHS > RHS
