Answer 1

Respuesta:

1) 4

2) 11

3) 233

Explicación paso a paso:

1) +(9-4-7)-(-7-9+10) ; +9-4-7= -2 -> -7-9+10= -6 ; -2-(-6) -> -2+6= 4

2) -1-(-8+1)+(-3-14-(-7)+(+13) ; -1+8+1= 8 -> -3-14+7= -10 + (+13) ; 8-10+13= 11

3) -(-5+9)·(+7-2)-(+4-2-3-7) ; +5+9= 45 -> +7-2= 5 -> +4-2-3-7= -8 ; 45·5-(-8) -> 225-(-8) -> 225+8= 233
