Explicación paso a paso:

Recuerda que se resuelve de izquierda a derecha y tambien que los contenidos del parentesis se hacen primero

1.-

$15 + (26 - 12) - 8\\\\26 - 12 = 14\\\\15 + 14 = 29 - 8 = 21$

2.-

$(22+4)-17 + 5\\\\22+4 = 26\\\\26 - 17 = 9 + 5 = 14$

3.-

$(9+8) + (16-9)\\\\9+8 = 17\\16-9=7\\\\17+7=24$

4.-

$25 + 12 + (8-5) + 2 \\\\8-5 = 3\\\\25+ 12 = 37 + 3 = 40 + 42$

5.-

$32-(12-6) + 8 -4\\\\12 - 6 = 6\\\\32 - 6 = 26 + 8 = 34 - 4 = 30$

6.-

$76-42 +(12-6) + (3-10) -2\\\\12 - 6 = 6\\3-10=7\\\\76 - 42 = 34 + 6 = 40 + 7 = 33 -2 = 31$

7.-

$(50 - 20)- (30 + 20) + 8-38\\\\50 - 20 = 30 \\30 + 20 = 50\\\\30 - 50 = -20 + 8 = -12 - 38 = -50$

8.-

$10 - (5 + 5) - 3+ (15 + 18) - 6\\\\5+5=10\\15+18 = 33\\\\10 - 10 = 0 - 3 = -3 + 33 = 30 -6 = 24$

9.-

$45+ (42-18 + 6) - 18 + 9 -6\\\\42 - 18= 24 + 6 = 30\\\\45 +30 = 75 - 18 = 47 + 9 = 56 - 6 = 50$

10.-

$17 + 26-(15-8) + (8-4) + 9\\\\15 - 8 = 7\\8-4 = 4\\\\17 + 26 = 41 - 7 = 34 + 4 = 8 + 9 = 17$
