Q.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)


Answer :

(a) (-3) + (-6) = -9
(-3) – (-6) = -3 + 6 = 3
-9 < 3
\(\Therefore \) (-3) + (-6) < (-3) – (-6)
(b) -21 – (-10) = -21 + 10 = -11
-31 + (-11) = -42
-11 > -42
\(\Therefore \) (-21) – (-10) > (-31) + (-11)
(c) 45 – (-11) = 45 + 11 = 56
57 + (-4) = 57 – 4 = 53
56 > 53
\(\Therefore \) 45 – (-11) > 57 + (-4)
(d) (-25) – (-42) = -25 + 42 = 17
-42 – (-25) = -42 + 25 = -17
17 > -17
\(\Therefore \)(-25) – (-42) > (-42) – (-25)
