Answer 2

Respuesta:

Explicación paso a paso:

A) -14 – {-29 – [15 – (16 + 31)] – [-12 + (-48 - 77)]}

-14-{-29-[15-(47)]-[-12+(-125)]}

-14- { -29 - [15-47] - [-12-125]}

-14 - { -29-[-32]-[-137]}

-14- { -29+32+137}

-14-{140}

-14-140=-154

b) –{34 – 85 – [47 – (53 – 72 - 96) - 58] – [-23 – (47 - 85)]}

- {-51- [47-(-115)-58] - [-23-(-38)]}

- { -51- [47+115-58] - [-23+38]}

- { -51- [104] - [15]}

- { -51-104-15}

- { -170}=+170

c) - 25 – (-84) + {-59 – [-68 + (35 - 94)] – [49 – 75 - 68]}

-25+84+{ -59- [-68+(-59)] - [-94]}

59+{ -59- [ -68-59] +94}

59-59- [-127] +94

0+127+94=221
