Answer 1

Respuesta:

Explicación paso a paso:

1 )

$-\left(5\right)-\left(-10\right)-\left(2\right)+\left(-1\right)\\\\=-\left(5\right)+10-\left(2\right)+\left(-1\right)\\\\=5-\left(2\right)+\left(-1\right)\\\\=3+\left(-1\right)\\\\=3-1\\\\=2$

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

2 )

$=\left(-10\right)-12-\left(-1\right)+12-\left(-4\right)\\\\=-22-\left(-1\right)+12-\left(-4\right)\\\\=-22+1+12-\left(-4\right)\\\\=-21+12-\left(-4\right)\\\\=-9-\left(-4\right)\\\\=-9+4\\\\=-5$

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

3 )

$\left(-5\right)+\left(7\right)-\left(6\right)+\left(-20\right)\\\\=5+\left(7\right)-\left(6\right)+\left(-20\right)\\\\=12-\left(6\right)+\left(-20\right)\\\\=6+\left(-20\right)\\\\=6-20\\\\=-14$

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

4 )

$8-5+4-2-\left(-6+2-7+10\right)-\left(15\right)\\\\-6+2-7+10\\\\=-4-7+10\\\\=-11+10\\\\=-1\\\\=8-5+4-2-\left(-1\right)-\left(15\right)\\\\=-9$

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

5 )

$-\left(-2+4\right)+\left(-8+2\right)-\left(-6\right)\\\\=-2+\left(-8+2\right)-\left(-6\right)\\\\=-2-6-\left(-6\right)\\=-2$

listo . saludos!!!!!
