How to pronounce mathematics in American English
ma·thuh·MA·tuhks
Start here
Americans pronounce mathematics as ma-thuh-MA-tuhks (/ˌmæθəˈmæɾəks/). In "mathematics", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, and it's one of the defining features of casual American English. It comes out as MA·thuh·MA·tuhks. Stress falls on the third syllable — keep everything else short and quick. You'll hear it in sentences like "She finds mathematics thought-provoking".

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Saying a hard "T" in the middle.
In "mathematics", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
ma-thuh-MA-tuhks→MA·thuh·MA·tuhks
02
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch MA — keep everything else short and quick.
ma·THUH·MA·TUHKS→MA·thuh·MA·tuhks
03
Pronouncing the unstressed syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.

Questions
Questions people ask about this.
How is "mathematics" stressed in American English?
Stress falls on the third syllable — say "MA" with a longer, fuller vowel and keep every other syllable short and quick. The respell "ma-thuh-MA-tuhks" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why doesn't the T sound like a T in "mathematics"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "mathematics" sounds closer to "ma-thuh-MA-tuhks" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Why does the second syllable in "mathematics" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "ma-thuh-MA-tuhks" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "mathematics" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "ma-thuh-MA-tuhks" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
