Answer 1

Explicación:

• a) (+10)-(-9)+(-4)
• = 10 + 9 - 4
• = 19 - 4
• = 15

• b) (-2)-(+1)-(-9)+(-5)-3
• = -2 - 1 + 9 - 5 - 3
• = - 11 + 9
• = - 2

• c) 4-(+15)-(-6)+(-5)
• = 4 - 15 + 6 - 5
• = 10 - 20
• = - 10

• d) -20+(-5)+7-(-10)-(-2)-5-(+6)
• = -20 - 5 + 7 + 10 + 2 - 5 - 6
• = - 36 + 19
• = - 17

• e) -5-9+3+2+6-1+4
• = - 5 - 9 + 3 + 2 + 6 - 1 + 4
• = - 15 + 15
• = 0

• f) (8)-(+12)+(-5)+(-3)+1
• = 8 - 12 - 5 - 3 + 1
• = - 20 + 9
• = - 11

• g) -15+(-30)+5-(-8)-10
• = - 15 - 30 + 5 + 8 - 10
• = - 55 + 5 + 8
• = - 42

• h) (+2)-(-10)+(-5)+(-3)-(-1)+(-17)
• = 2 + 10 - 5 - 3 + 1 - 17
• = 13 - 25
• = - 12

• i) -(-12)+(-6)+(-30)+2-(-9)-(-11)
• = 12 - 6 - 30 + 2 + 9 + 11
• = - 36 + 34
• = - 2
