Fill in the blanks:

(a) (-8) + ….. = 0

(b) 13 + ……. = 0

(c) 12 + (-12) = ……..

(d) (-4) + …… = -12

(e) …… - 15 = -10

(a) We have,


= - 8 + 8 


= 0


 


(b) We have,


= 13 + (- 13)


= 13 – 13


= 0


 


 


(c) We have,


= 12 + (-12)


= 12 – 12


= 0


 


 


(d) We have,


= (- 4) + (- 8)


= - 4 – 8


= - 12


 


(e) We have,


= 5 – 15


= - 10
