Auckland maths teacher Subash Chandar K has a slightly larger classroom than most teachers, reaching tens of thousands of NCEA-level students with his maths video tutorials.
He livestreams on YouTube from his lounge at night, showing how to solve maths problems, as well as going though practice NCEA exams, step-by-step.
He's been making the videos for 10 years, and now has over 35,000 subscribers to his 'Infinity Plus One' channel, and last year had one million views of his videos.
Subash Chandar K is a teacher at Ormiston Junior College in Auckland.
