Explicación paso a paso:

12-(7 + 3)+(8-5)-3+(2+ 7) =

12-(10)+(3)-3+(9) =

12-10+3-3+9 =

12-10+3-3+9 = 11

4 + 6+ (5-3+6)-4-(12-9) =

4 + 6+ (8)-4-(3) =

4 + 6+ 8-4-3 = 11

(45+ 5-4)+(15+ 10-12) =

(50-4)+(25-12) =

(46)+(13) =

46+13 = 59

8-6+(9-5)+12-(3+2-1) =

8-6+(9-5)+12-(5-1) =

8-6+(4)+12-(4) =

8-6+4+12-4 = 14

2×(5+8) - 9:(4-1) +9=

2×(13) - 9:(3) +9=

26 - 3 +9= 32

5×(9+1)-3×(4-2) +8×(9-1)=

5×(10)-3×(2) +8×(8)=

50-6 +64= 108

(7+2)×(8+6)+(3+4)×(5-2)=

(9)×(14)+(7)×(3)=

126+21= 147

1+(12:3+4):2=

1+(12:7):2=

1+(8):2=

1+4= 5

5×4-(3 + 14:2)=

5×4-(10)=

20-(10)=10

Espero sea de ayuda :)
