c) - 1586 + (- 1275)-(-100 ) =

Answer 1

Respuesta:

a) -(+8) + (-27)-(-36 ) =  

$=-\left(8\right)-27-\left(-36\right)\\=-35-\left(-36\right)\\=-35+36\\=1$

-----------------------------------------------------

b) +300 + (-450 ) + ( +850 ) - ( + 1200 ) =

$=300-450+\left(850\right)-\left(1200\right)\\=-150+\left(850\right)-\left(1200\right)\\=700-\left(1200\right)\\=-500$

-----------------------------------------------------

c) - 1586 + (- 1275)-(-100 ) =

$=-1586-1275-\left(-100\right)\\=-2861-\left(-100\right)\\=-2861+100\\=-2761$
