Tolong di jawab secepatnya dan harus benar!!!!

1. -12+19-(-15)=
2. 11-(-20)+(-10)=
3. 12-[(-17)-28]=
4. 23-[(-17-28]=
5. -30-[45-(-27)]=

Answer 1

1) 7 + 15 = 22

2) 31 - 10 = 21

3) 12 - ( -45) = 57

4. 23 - (-45) = 68

5. -30 - (72) = -102

Answer 2

Penyelesaian :

1.) -12 + 19 - (-15) = 7 + 15 = 22
2.) 11 - (-20) + (-10) = 31 - 10 = 21
3.) 12 - [(-17) - 28] = 12 - (-45) = 57
4.) 23 - [(-17) - 28] = 23 - (-45) = 68
5.) -30 - [45 - (-27)] = -30 - (72) = -102

Semoga membantu ya.
