(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

(10) A number of solutions can be possible e.g., –20 – (–9) = –11

(11) A number of solutions can be possible e.g., –3 × 5 = –15

(12) A number of solutions can be possible e.g., 4 × 6 = 24.
