Answers:-
(1) A number of solutions can be possible e.g., 4 + (–6) = –2
(2) A number of solutions can be possible e.g., 8 + (–2) = 6
(3) A number of solutions can be possible e.g., –7 – (2) = –9
(4) A number of solutions can be possible e.g., 4 – (–3) = 7
(5) A number of solutions can be possible e.g., –12 – (–7) = –5
(6) A number of solutions can be possible e.g., –4 + (–7) = –11 < –10
(7) A number of solutions can be possible e.g., –1 – 4 = –5 < –4
(8) A number of solutions can be possible e.g., –8 – (–9) = 1 > –6
(9) A number of solutions can be possible e.g., –2 – (–10) = 8
