Answer 1

Respuesta:

45 – (–32) + (–12) – |–7| =58

22 – (–7 + (–12) – 19) + 13=73

[–32 + 43 – (–18)] + [43 – (–15)]=87

[54 – 32 + (–42)] – (12 – |–8|) =−24

–77 + [–56 – 65 – 54 + (–8)] =−260

– [98 + (–67) – (32) + (–12) – 5]=18

65 – 45 + (–8) – (–43) + 7 =62

43 – (–12) + (–8) + 40 – 53 =34

–76 – (–61) + (–13) – [–4 + (–6)]=−18
