\(A=\) \((\)\(\dfrac{2}{199}\) - \(\dfrac{3}{398}\)\()\) \(.\) \(\dfrac{199}{17}\)+\(\dfrac{33}{34}\)=\(\dfrac{2}{17}\) - \(\dfrac{3}{34}\)+\(\dfrac{33}{34}\)= 1
\(B=\) (\(\dfrac{7}{2009}\)+\(\dfrac{11}{4018}\)) . \(\dfrac{2009}{25}\)+\(\dfrac{9}{2}\)=\(\dfrac{7}{25}\)+\(\dfrac{11}{50}\)+\(\dfrac{9}{2}\)=5
\(A+B = 1 + 5 = 6\)
\(A - \)\(\dfrac{1}{5}\) . \(B=1 -\)\(\dfrac{1}{5}\). 5 = 1 \(-\) 1 = 0
