Answer 1

Respuesta:

Explicación paso a paso:

a) 5 – [ - 3 – 2 + ( - 5)] + (- 5 – 7)

5-[-3-2-5]+(-12)

5-[-10]-12

5+10-12

b) – 2 { [7 + 3 + (-3) –(-5)] – ( -2 – 4 – 3)}

-2{[7+3-3+5]-(-9)}

-2{12+9}

-2{21}

-42

c) – 6 – 5 x (-3) – (-3 -7) + 15 – 5

-6+15-(-10)+15-5

-6+15+10+15-5

d) 8 – 4 + { 9 – 7 + ( 3 + 6 -24 ) - [12 + (- 2 – 3)] - 2 + 2

8-4+{9-7+(-15)-[12+(-5)]}-2+2

8-4+{9-7-15-[12-5)]}-2+2

8-4+{9-7-15-7}-2+2

4-20-2+2
