Answer 1

Solución :

• +(-4-7+)-3-4-5-8)
-4-7-3-4-5-8
-11 -7 -13
-18 -13
-31.

R = -31.

• -(+3-2-1)+(-5+7+4)
-3-2-1-5+7+4
-5 -6 +11
-11 +11
0.

R = 0.

• -(5+6-3+6)+3-(+5-2+1)
-5+6-3+6+3-5-2+1
+1 +3 -2 -1
4 -3
1.

R = 1.

• -2-4+(-8+4-6+7)
-6 -8 +4-6+7
-14 -2 +7
-16 +7
-9.

R = -9.

• -(+2-3+5)+(-2+6-4+7)
-2-3+5-2+6-4+7
-5 +3 +2 +7
-2 +9
+7.

R = +7.

• -(+4-6-9)+(-4+5-2)
-4-6-9-4+5-2
-10 -13 +3
-23 +3
-20.

R = -20.

• +(-3+5+2+2)-(-8-4-5)
-3+5+2+2+8-4-5
+2 +4 +4 -5
+6 -1
+5.

R = +5.

• +(-8-3-9)+4+(-2+9)
-8-3-9+4-2+9
-11 -5 +7
-16 +7
-9.

R = -9.

• +(-4+7+2)+9-(-3+4-3)
-4+7+2+9+3+4-3
+3 +11 +7 -3
14 +4
18.

R = 18.

• -(5-3)-(+4+7+2+3)
-5-3-4+7+2+3
-8 +3 +5
-5 +5
0.

R = 0.
