You're standing in a classroom in London. You look at the chalkboard—or maybe a smartboard these days—and you see the word "Maths" written in bold letters. Now, hop on a flight to New York. Walk into a school there, and suddenly that "s" has vanished into thin air. It’s just "Math." It feels like a glitch in the matrix, doesn't it? One tiny letter causing a massive international divide. People get surprisingly heated about this. I’ve seen internet forums devolve into digital shouting matches over whether that extra consonant belongs there or if it’s just grammatical clutter. Honestly, it’s one of those linguistic quirks that tells you exactly where a person grew up before they even finish their sentence.
The reality of how to spell maths isn't just about being right or wrong. It’s about history, geography, and how we perceive the very nature of the subject.
The Great Atlantic Divide: Why Americans Hate the S
If you grew up in the United States or Canada, "maths" sounds inherently wrong. It sounds clunky. It feels like someone trying too hard to be British. In North America, the word is "math," end of story. This isn't just a slang choice; it’s the standard used by the American Mathematical Society and every major textbook publisher from Pearson to McGraw Hill.
But why?
Etymologically, both versions are clippings. We’re all just shortening the mouthful that is "mathematics." In the US, the logic is simple: you take the first part of the word and stop. It’s a singular mass noun. You don't say "theories of physics are hard," you say "physics is hard." So, Americans treat math the same way. It's an uncountable concept. You have some math to do, not some maths to do.
Interestingly, this wasn't always a hard rule. If you look at colonial-era documents, spelling was a bit of a Wild West situation. Noah Webster, the man behind the famous Webster’s Dictionary, had a massive hand in this. He wanted American English to be distinct, streamlined, and logical. He’s the reason Americans write "color" instead of "colour." While he didn't single-handedly kill the "s" in math, his influence on "Americanizing" the language set the stage for the shorter version to become the undisputed king of the states.
How to Spell Maths in the Rest of the World
Now, if you’re in the UK, Australia, New Zealand, or even parts of India, the "s" is non-negotiable. To a British ear, saying "I have math class" sounds like you’ve forgotten to finish the word. It sounds naked.
The British logic for how to spell maths is actually quite robust. They argue that because "mathematics" ends in an "s," the shortened version must retain that "s" to respect the plural-sounding nature of the original Greek mathematika.

Think about it.
Mathematics is a collection of different disciplines. You’ve got geometry, algebra, calculus, and statistics. It’s a plural concept. Therefore, "maths" feels more representative of the variety within the field. If you go to Oxford or Cambridge, you won't find a "Math Department." You'll find a Department of Mathematics, and the students will tell you they are "doing maths."
I once spoke with a linguist who pointed out that this is one of the few areas where British English is actually more "logical" in its abbreviation than American English, even though American English usually prides itself on being the more efficient version. It’s a rare reversal of the usual linguistic roles.
Is Mathematics Actually Plural?
This is where things get nerdy.
Is the word mathematics actually plural? In modern English, no. We treat it as a singular noun. We say "Mathematics is the language of the universe," not "Mathematics are the language of the universe." This is what linguists call a singular tantum—a word that looks plural but functions as a singular.
Because of this, the American "math" is technically more grammatically consistent with how we use the word in a sentence. We don't say "gymnastics are fun" or "economics are confusing." We treat those "-ics" words as singular blocks of study.
However, the British "maths" defenders aren't wrong about the origins. The Greek root is plural. The Latin mathematica was plural. It wasn't until the 17th century that the word began to be treated as a singular mass noun in English. So, when you're wondering how to spell maths, you're really choosing which century's logic you want to follow.

The Oxford English Dictionary Weighs In
The OED is usually the final boss of these arguments. According to their records, the word "math" (without the s) first appeared in print around 1847. The British version, "maths," showed up a bit later, around 1911.
Wait.
Did you catch that?
The "American" version actually has an older recorded usage than the "British" one. This usually blows people's minds. Most people assume the British version is the "original" and the Americans chopped it down out of laziness or a desire for efficiency. But the written evidence suggests that "math" was the first shortened form to gain traction in the English-speaking world.
It wasn't until the early 20th century that "maths" became the standard in the UK. This suggests that the divide isn't an ancient one. It’s a relatively modern branding split.
Pop Culture and the Spread of Math
Language isn't static. It's constantly moving. Thanks to Hollywood, Netflix, and the global dominance of American tech, the word "math" is creeping into places where it didn't used to be.
You’ll see it in TikTok captions from creators in London. You'll hear it in songs by artists who definitely didn't go to school in Kansas. This "Americanization" of the word bothers some people deeply. There’s a sense of cultural loss when a local dialect gives way to a globalized version.

But it goes both ways.
With the rise of British shows like Skins or Doctor Who on global streaming platforms, Americans are becoming much more familiar with the "s." It’s no longer a confusing typo; it’s just recognized as "the way they say it over there."
Common Mistakes When Writing the Word
Regardless of which side of the pond you're on, people still mess up the spelling and usage.
- The Apostrophe Trap: Never, ever put an apostrophe before the "s" in maths. It’s not "math's." An apostrophe indicates possession or a contraction (like "math is"). If you're just shortening mathematics, no apostrophe is needed.
- Capitalization: Unless "Math" or "Maths" is the first word in a sentence or part of a specific course title (like Math 101), it shouldn't be capitalized. It’s a common noun, just like science or history.
- The "Maths is" vs "Maths are" debate: Even in the UK, where the "s" is present, the verb remains singular. "Maths is my favorite subject" is correct. "Maths are my favorite subject" sounds weird even to a Londoner.
How to Decide Which One to Use
If you are writing for a specific audience, the choice is made for you.
- Writing for a US or Canadian audience? Use Math. Using "maths" will make you look like you’re trying too hard or simply don't know the local conventions. It can actually hurt your credibility in a professional or academic setting in North America.
- Writing for the UK, Australia, India, or Ireland? Use Maths. In these regions, "math" is often seen as an "Americanism" and can be viewed as a sign of poor education or too much time spent watching American TV.
- Writing for a global, neutral audience? This is the tricky part. Usually, it's best to stick to the version used by the organization you're representing. If you're a freelance writer, ask for the "house style." If you don't have one, pick one and be consistent. Nothing looks worse than switching between "math" and "maths" in the same article.
Beyond the Spelling: The Feeling of the Word
Language is emotional. "Math" feels fast. It feels like a quick calculation on a napkin. "Maths" feels a bit more formal, a bit more academic. It’s fascinating how a single letter can change the "vibe" of a sentence.
When you're teaching a child how to spell maths, you're teaching them more than just letters. You're teaching them where they fit in the global English-speaking community. You're giving them a linguistic passport.
Actionable Steps for Perfect Usage
Stop stressing about which one is "better." Neither is. They are both correct within their respective geographies.
- Check your spellcheck: Set your Google Docs or Microsoft Word language settings to the specific region of your audience (English UK vs. English US). This is the easiest way to avoid "correcting" yourself into an error.
- Audit your consistency: If you’re writing a long paper, use the "Find" function (Ctrl+F) to search for both versions. Ensure you haven't accidentally used both.
- Observe the context: If you're writing a story set in London, your characters must say "maths." If they say "math," you've broken the immersion for your reader.
- Respect the "Mathematics": If you want to avoid the debate entirely, just use the full word. "Mathematics" is universally accepted, professional, and avoids all regional bickering. It’s the safe haven of the academic world.
The debate over how to spell maths isn't going away anytime soon. It's a badge of identity. Whether you keep the "s" or drop it, you're participating in a linguistic tradition that spans centuries and oceans. Just pick your side, stay consistent, and for heaven's sake, don't use an apostrophe.
