Question 2 (c)
Fill in the blanks with >, < or = sign:
45 – (–11) ___ 57 + (–4)
LHS = 45 - (-11) = 45 + 11 = 56
RHS = 57 + (-4) = 57 - 4 = 53
56 > 53
∴ 45 – (–11) > 57 + (–4)
Question 2 (b)
(–21) – (–10) ___ (–31) + (–11)
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)
