if you are adding two negative numbers, the number is greater

if you are taking a positive number and adding a negative number to it you subtract

so like the answer to number three, -51 + -9 your answer is negative 60, number four your answer is 21, number seven your answer is 43, number 8 your answer is -34 number 11 your answer is 6 number 12 your answer is 12 hopefully you catch on

Step-by-step explanation:

1. -51 + (-9) = -60

2. 27 + (-6) = 21

3. 1 + (-30) = -29

4. 15 + (-25) = -10

5. 50 + (-7) = 43

6. -19 + (-15) = -34

7. (-23) + 9 = -14

8. -19 + (-21) = -2

9. -17 + 11 = -6

10. 20 + (-8) = 12

11. (-15) + (-7) = -22

12. 12 + (-14) = -2

i think the answer is seven, for if i'm being useless °ω°
