Answer 1

Объяснение:

(+9) + (+7) = 9+7 = 16

(+7) + (+5) = 7+5= 12

(-1) + (+3) = –1+3= 2

(-6) + (-7) = –6-7= –13

(–2) + (–6)= –2–6= –8

(–5) + (–9) = –5–9= –14

(–5) + (+4) = –5+4= –1

(–1) + (–8) = –1–8= –9

(+7) + (–4) = 7–4= 3

(+9) + (+3) = 9+3= 12

(+7) + (–1) = 7–1= 6

(–5) + (+9) = –5 + 9= 4

(+8) + (+4) = 8+4= 12

(+7) + (+8) = 15

(+9) + (–4) = 9–4= 5

(–5) + (–6) = –5–6= –11

(–3) + (–9) = –3–9= –12

(–7) + (–4) = –7–4= –11

(–6) + (+9) = –6+9 = 3

(+2) + (–5) = 2–5= –3
