Respuesta:

 - 12 + 26 -8 + 15 + 23 – 20 - 25 + 10 =

$=14-8+15+23-20-25+10\\=6+15+23-20-25+10\\=21+23-20-25+10\\=44-20-25+10\\=24-25+10\\=-1+10\\=9$

 - 5 + (-6) - (-5) + (-9) – (+7) + (-10) + 7 – 12 =

$=-5-6-\left(-5\right)+\left(-9\right)-\left(7\right)+\left(-10\right)+7-12\\=-11-\left(-5\right)+\left(-9\right)-\left(7\right)+\left(-10\right)+7-12\\=-11+5+\left(-9\right)-\left(7\right)+\left(-10\right)+7-12\\=-6+\left(-9\right)-\left(7\right)+\left(-10\right)+7-12\\=-6-9-\left(7\right)+\left(-10\right)+7-12\\=-15-\left(7\right)+\left(-10\right)+7-12\\=-22+\left(-10\right)+7-12\\=-25-12\\=-37$

 [-6 + (4 + 2 ) – (-9) ] - [(-4) – (+7 - 5) + (-12) ] +7 – 15 =

$=9-\left[\left(-4\right)-\left(7-5\right)+\left(-12\right)\right]+7-15\\=9-\left(-18\right)+7-15\\=19$

 4 + { [ -7 + (3 + 2) - (-2) ] + [ ( -3 ) – ( +8 -8) + (-10) ] ) } + 10 – 3 =

$=4+0+\left[\left(-3\right)-\left(8-8\right)+\left(-10\right)\right]+10-3\\=4+0-13+10-3\\\\=-2$
