'Zero Divided by Zero Equals Nothing'; slang for "Good for Nothing"), released internationally as The New Classmate, is a 2015 Indian Hindi-language comedy drama film directed by Ashwiny Iyer Tiwari in her feature debut.

Swara Bhaskar starred as Chanda Sahay, a high-school drop-out household maid and single mother of a sullen young girl named Apeksha, played by Riya Shukla.

Released in India on 22 April 2016, Nil Battey Sannata was distributed by Eros International and garnered critical and audience acclaim.

Apeksha "Apu" Shivlal Sahay (Shukla) is an unmotivated student who has managed to reach her SSC year in school despite her lack of interest in studying further.

Troubled by her daughter's indifferent attitude, Chanda narrates her dilemma to Dr. Diwan, who suggests that she hire a math tutor for Apu.

She enlists the help of her shy classmate Amar (Vishal Nath) to understand math and makes use of mind maps on his advice.

Chanda stops attending school and continues to work with the hope that Apu will join the Indian Administrative Service (IAS), after she is inspired by a kind District Collector (Sanjay Suri).
