Dear Student

(a) 137 and -354 (137) + (-354)
= (317) + (-137) + (-217)
= 0 + (-217) [(317) + (-317)= 0]
= (-217)

(b) -52 and 52
(-52) + (+52) = 0
[(-a) + (+a) = 0]

(c) -312, 39 and 192

(-312) + (+39) + (+192)
= (-231) + (-81) + (+39) + (+192)
= (-231) + (-81) + (+231)
= (-231) + (+231) + (-81)
= 0 + (-81) [(-a) + (+a) = 0]
= -81


Thanks
