用英语如何表达数学

Expressing mathematics in English can be done using a combination of words and symbols that convey the same concepts as in any other language. Here's a simple breakdown:

Numbers: Use Arabic numerals (1, 2, 3, etc.) or words like "one," "two," "three," etc.

Addition: "Add," "plus," "sum," "and."

Example: "Three plus two equals five."

Subtraction: "Subtract," "minus," "difference."

Example: "Ten minus three is seven."

Multiplication: "Multiply," "times," "product."

Example: "Four times three is twelve."

Division: "Divide," "by," "quotient."

Example: "Eight divided by two is four."

Equations: Use the equals sign (=) to denote equality.

Example: "x + 3 = 5"

Fractions: Use "a over b" or "a/b" for fractions.

Example: "Two-thirds" translates to "2/3."

Square Roots: "The square root of" or "√" symbol.

Example: "The square root of nine is three."

Geometry: Words like "point," "line," "angle," "circle," etc.

Example: "A right angle is 90 degrees."

Variables: Use letters like x, y, z for unknowns.

Example: "The value of x when y is 2 is 4."

Remember, in English, the order of operations (PEMDAS/BODMAS) also applies: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
