Me ayudan plis es para hoy mismo :c

Answer 1

– 3 + (8 – 2)

– 3 + 6

+ 3

9 + [- 5 + (- 4 - 2) ] + 6 =

9 + [- 5 + (- 6) ] + 6

9 + [- 5 - 6 ] + 6

9 + [- 11 ] + 6

9 - 11 + 6

9 + 6 - 11

15 - 11

4

[(40 ÷ - 4) + (14 ÷ 2)] + (4 x - 2)  

[(-10) + (+7)] + (-8)  

[-10 +7] -8  

[-3] -8

- 3 - 8

- 11  

(8 x 3) ÷ (- 6 x 4)

24 : - 24

-1

– 15 - {[– 5 + (25 + 10) – 20] + 9}

– 15 - {[– 5 + (35) – 20] + 9}

– 15 - {[– 5 + 35 – 20] + 9}

– 15 - {[ 35 - 5 – 20] + 9}

– 15 - { [ 30 – 20] + 9 }

– 15 - { [ 10] + 9 }

– 15 - { 10 + 9 }

– 15 -  10 - 9

- 34
