A = - \(\dfrac{3}{31}\) - \(\dfrac{6}{17}\) + \(\dfrac{1}{2}\) - \(\dfrac{28}{31}\) - \(\dfrac{11}{17}\)- \(\dfrac{1}{6}\)
A = -( \(\dfrac{3}{31}\) + \(\dfrac{28}{31}\)) - ( \(\dfrac{6}{17}\) + \(\dfrac{11}{17}\)) +( \(\dfrac{1}{2}\)- \(\dfrac{1}{6}\))
A = - \(\dfrac{31}{31}\) - \(\dfrac{17}{17}\)+ \(\dfrac{1}{3}\)
A = -1 - 1 + \(\dfrac{1}{3}\)
A = \(-\dfrac{5}{3}\)
