Explicación paso a paso:
a) (6-5+7)-(3-2-8)= b)(2-5)-(3-7)-(6+1)=
8-(-7)= -3-(-4)-7=
8+7= -3+4-7=
15 -6
c)8-(5-2+4-2)= d)5-(3-10)+(4-8+2)-(7-5+1)
8-5= 5-(-7)+(-2)-3=
3 5+7-2-3=
7
e)-(-2+10-3)+(7-9)-(1-2+9)= f)2-(6-(12-3-1))-8=
-(5)+(-2)-(8)= 2-(6-8)-8=
-5-2-8= 2-(-2)-8=
-15 2+2-8=-4
g)15-(13-(6-8))= h)(6-10)-((5-3)-(4-6))=
15-(13-(-2))= -4-(2-(-2))=
15-15=0 -4-4=-8
i)16-(1-(5-(3-1)+(2-8))-20=
16-(1-(5-2+(-6))-20=
16-(1-3)-20=
16-(-2)-20=
16+2-20=
-2
