Infinityplusone

Infinityplusone is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Infinityplusone rather than just read about it. In short: Subash Chandar K (born 1981 or 1982) is an Indian-New Zealand mathematics teacher in Auckland. He runs a YouTube channel named infinityplusone, where he teaches secondary school students and prepares them for NCEA exams.

Key takeaways

Infinityplusone belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Infinityplusone to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Infinityplusone from memory before moving on to harder problems.

Reference excerpt

Subash Chandar K (born 1981 or 1982) is an Indian-New Zealand mathematics teacher in Auckland. He runs a YouTube channel named infinityplusone, where he teaches secondary school students and prepares them for NCEA exams. In 2025 Chandar K was awarded the Local Hero of the Year award at the New Zealander of the Year Awards.

Biography Chandar K moved from Chennai, India, to New Zealand aged 12. His mother was a maths professor in Chennai. As of 2025, Chandar K lives in Auckland and teaches at Ormiston Junior College in Flat Bush. His YouTube channel infinityplusone has 70,700 subscribers as of July 2026, and was named after the amount he loved his wife. On the channel he helps students prepare for NCEA exams by running live streams the nights before the exams are run, and makes videos which explain how to use equations and calculators. The channel was started in 2013 because Chander K noticed a lack of maths videos designed for children. His first live stream was in 2018. In 2018 Chandar K won the National Excellence in Education Awards top honour. In January 2025 Chandar K became one of the 10 finalists of the Global Teacher Prize. Chandar K said that after he discovered the award in 2017, he began working towards it. In March 2025 Chandar K was awarded the Local Hero of the Year award at the New Zealander of the Year Awards.

Worked examples

Example 1 — a first encounter with Infinityplusone

Start with the simplest possible case. Write down what Infinityplusone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Infinityplusone before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Infinityplusone ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Infinityplusone

In research: Infinityplusone appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Infinityplusone in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Infinityplusone is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s births, Educators from Auckland, Indian mathematics educators, so understanding it makes those chapters shorter.
In everyday life: Look for Infinityplusone outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
