Resolva estas adições algébricas
-18+90-45-10+36
-59+27-16-1+8
-(-35+83-17-4)
-(+1-12+0+19+56)
-6-(-14+24-75-24)
57-(-6+34+20-9)

Answer 1

$-18+90-45-10+36\\{-}72-45-19+36\\{-}117-19+36\\{-}136+36\\= -100$

$-59+27-16-1+8\\{-}32-16-1+8\\{-}48 -1+8\\{-}49 +8\\= {-}41$

$-(-35+83-17-4)\\{-}(-48-17-4)\\{-}(-65-4)\\{-}(-69)\\= 69$

$-(\not\!+1-12+0+19+56)\\{-}(-11+\!\not\!0\,+19+56)\\{-}(-8+56)\\= -48$

$-6-(-14+24-75-24)\\{-}6-(10-75-24)\\{-}6-(65-24)\\{-}6-41\\= {-}47$

$57-(-6+34+20-9)\\57-(28+20-9)\\57-(48-9)\\57-39\\= 18$

Espero ter ajudado!
