urgent dau coroan si multe puncte

Answer 1

• [+72–(–96):(–12)–(–84):(–6)]:(–25) =

= (72-8-14) : (-25) =

= 50 : (-25) =

= -2

• [–84–(–99):(–11):(–3)+(+63):(–21)]=

= -84-9:(-3)+(-3) =

= -84+3-3 =

= -84

• [–68–(–32):(–16)–(+46):(–23)]:(–34) =

= [-68-2-(-2)] : (-34) =

= (68-2+2) : (-34) =

= 68 : (-34)

= -2

• [+86–(–75):(–15)–(–85):(–5)]:(–16) =

= (86-5-17) : (-16) =

= 64 : (-16) =

= 4
