Introduction
Many students wonder whether they should write maths or math. Both words are commonly seen online, in books, and in videos, so it is easy to feel confused.
For students in Singapore, the answer is simple: Singapore generally follows British English, so the correct school usage is usually maths with an s. Americans commonly say math, while Singapore students are more likely expected to say and write maths.
Understanding maths or math is not just about one word. It also helps students notice the difference between British and American English in everyday spelling and pronunciation.

The Question / Scenario Explanation
Source: Maths or Math — which one is correct?
The screenshots show a teacher explaining that if students say “math” in Singapore, it is technically not the usual local school form. Singapore follows British English, and in British English, the word is usually written and said as maths.
The video explains:
- British English: maths
- American English: math
- Singapore school usage: maths
The video also gives other examples of British-style pronunciation and usage, such as:
- law, not “lor”
- flour, not “flower”
- neither, not “neither” with the wrong pronunciation
- schedule, not the American-style pronunciation
The main idea is that students should be aware of British English because it is the standard usually used in Singapore schools.
Step-by-Step Solution / Explanation
Step 1: Understand That “Maths” and “Math” Come from Different English Systems
The word mathematics can be shortened in different ways depending on the English variety.
In British English, it is commonly shortened to:
maths
In American English, it is commonly shortened to:
math
This means both forms exist, but they are used in different contexts.
Step 2: Know What Singapore Usually Uses
Singapore schools generally follow British English. That is why students usually see and hear:
- Maths lesson
- Maths homework
- Maths exam
- PSLE Maths
- O Level Maths
So for school writing in Singapore, maths is the safer and more suitable choice.
Step 3: Understand Why “Math” Appears So Often Online
Students may still see the word math very often because many online platforms, apps, worksheets, and videos use American English.
For example, students may see:
- math games
- math tricks
- math worksheets
- math tutorials
This does not mean maths is wrong. It simply means the content may be using American English.
Step 4: Apply the Correct Form in Singapore School Writing
When writing for school in Singapore, students should usually write:
- I have Maths homework today.
- My favourite subject is Maths.
- She is revising for her Maths exam.
- PSLE Maths requires careful working.
These examples follow the British English style commonly used in Singapore.
Step 5: Avoid Mixing British and American English
The key is consistency. If students are writing in British English, they should try not to mix in American forms unnecessarily.
For example, this may look inconsistent:
- I have a maths test and a math worksheet.
A more consistent version for Singapore school writing would be:
- I have a Maths test and a Maths worksheet.
Step 6: Remember That Context Matters
When deciding between maths or math, students should ask:
- Am I writing for school in Singapore?
- Am I following British English?
- Is this an American website or app?
- Should I keep my writing consistent?
For PSLE English, context matters because students need to choose language that suits the situation.
Step 7: Learn from Other British and American Differences
The same idea applies to other words too. For example:
- British: colour | American: color
- British: favourite | American: favorite
- British: centre | American: center
- British: programme | American: program
Once students notice these differences, they become more aware of English usage and can write more accurately.
Key Concepts Students Must Know
- “Maths” is British English: This is the form usually used in Singapore schools.
- “Math” is American English: This is commonly seen in American books, videos, apps, and websites.
- Singapore follows British English: Students should usually write Maths in school contexts.
- Both forms exist: The important thing is to use the correct form for the context.
- Consistency matters: Students should avoid mixing British and American usage in the same piece of writing.

A useful way to remember maths or math is this: in Singapore school writing, choose Maths. If you see math online, it is likely American English.
Parent Insight
Parents may notice that children pick up American English from YouTube, apps, online worksheets, and games. This is very common, especially because many digital learning platforms use American spelling and pronunciation.
At home, parents can help by gently reminding children that Singapore schools usually follow British English. You can ask:
- “Is this British or American English?”
- “Which one does your school usually use?”
- “Are you writing for a Singapore school assignment?”
- “Is your spelling consistent throughout the sentence?”
This helps children become more aware of language choices without making them feel that one English variety is “bad”. The goal is to use the right form for the right context.
Conclusion
So, should students write maths or math? In Singapore school contexts, the better choice is usually Maths, because Singapore follows British English.
Math is commonly used in American English, while maths is the British English form. Since Singapore schools generally use British English, students should write Maths in compositions, assignments, and exam-related contexts.
By understanding the difference, students can write more accurately and become more confident with British and American English usage.
