Answer 1

Respuesta:

5 + { +3 - 4 +[ 6 + (4 +3 -2) – (6 + 1) - 8 - 5] + [ 7 + (3 -1) +2 ] -3 } =

5+{+3-4+[6+(5)-(7)-13]+[7+(2)+2]-3}

5+{3-4+[6+5-7-13]+[7+2+2]-3}

5+{3-4+[-9]+[11]-3}

5+[3-4-9+11-3}

5-2

3

2 - { 3 + 5 - [4 + (3+2-8) – (- 4+3-7)] - [ 4 – (-1+2) + (8 - 3) +2] – 4 +2 } =

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

2-{3+5-[4-3+8]-[4-1+5+2]-4+2}

2-{3+5-9-10-4+2}

2-{-13}

2+13
