Eliminar signos de agrupación: A -[+4+5-[6+3-(2+1)+3]+8-5]= B -(7+11-[-5-(-2+3-5+4)]-6]= C +(-3+[-5-(-2+3-5+4) ] }= D -4-3-[-6+4+[-(-3+5) ] }= E +9-8-7+3-(-4-[+4]-8} - {+4-3}= F -[+5-(+4-2-3}+4]-[+3-(+5+2)+8]= G -n+9+(+4-[+3+9)-(+4+8-6-3)= AYUDA POR FAVOR, NO ENTIENDO

Answer 1

-[+4+5-[6+3-(2+1)+3]+8-5]

- [+9 - [9 - (3) +3] + 3 ]

- [+9 - [9 - 3 + 3 ] + 3 ]

- [+9 - [ 9 ] + 3 ]

- [+9 -  9  + 3 ]

- [ + 3 ]

- 3

-(7+11-[-5-(-2+3-5+4)]-6]

- ( 7 + 11 - [ - 5 - (+1 - 1 ) ]-6]

- ( 7 + 11 - [ - 5 - (+0) ] -6 ]

- ( 18 - [ - 5 ] - 6 ]

- ( 18 + 5  - 6 ]

- ( 23 - 6 ]

- ( + 17 ]

- 17
