The mathematical symbols and Greek letters that often appear in foreign languages are often difficult to pronounce and have to stop and get stuck. Many friends may have encountered this problem. I searched on the Internet and sorted out a list of mathematical symbols and Greek letters in Chinese and English pronunciation, including the address of the webpage on the Greek letter real-person pronunciation page of the application Mathematics Department of South China University of Science and Technology, hope to help people who see it.

Mathematical symbols content mainly from Peking University Chinese Forum: Tid-18288-page-1.html

Greek letter content mainly from Zhang Hao's blog: Logid = 159 & cateid = 7

South China University of Science and Technology Applied Mathematics Department Greek letter real people pronunciation webpage address:


+: Plus (positive)

-: Minus (negative)

*: Multiplied

Partition: divided

=: Be equal

≈: Be approximately equal

(): Round brackets (parenthess)

[]: Square brackets

{}: Braces

Usage: Because

Authorization: therefore

≤: Less than or equal

≥: Greater than or equal

∞: Infinity

: LogX to the base n

: The Nth Power of X

F (x): The function of X

DX: diffrencial of X

X + Y: x plus y

(A + B): bracket A plus B bracket closed

A = B: A equals B

A = B: A isn' t equal to B

A> B: A is greater than B

A> B: A is much greater than B

A ≥ B: A is greater than or equal to B

X → ∞: X approches infinity

: X square

: X cube

: The square root of X
