numeral symbol such as 0–9
One number sign, like 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, that is used to write a number.
用法模式：
a [number] with [number] digits
常见错误：
Learners sometimes confuse "digit" with "number". A digit is one symbol (0–9), while a number can have one or many digits (for example, 7 is a one-digit number, 27 is a two-digit number). Learners may also confuse "digit" (noun) with "digital" (adjective, as in "digital camera").

figure (Informal and common in speech; often used when talking about numbers in general, especially money or statistics.)
反义词

numerical place within a number
One place in a written number where a single numeral goes, like the units place, tens place, or the first place after the decimal point.
用法模式：
the [first/last] digit of [a number]
常见错误：
Learners may mix up the idea of a digit itself (the symbol) with its "place". A digit is the symbol, while this meaning focuses on its position in the number (for example, the "tens digit"). They may also say "the second number" instead of "the second digit" when they mean a place inside one number.
近义词
place (Shortened form of "place value"; used mainly in education when talking about positions in numbers.)
|
place value (More explicit term focusing on the value a digit has because of its position.)
反义词
whole number (Contrasts with talking about a single digit position by referring to the entire number as one unit.)

finger or toe in anatomy
A technical word in science for a finger or a toe, or a similar part on an animal’s foot.
用法模式：

finger (Everyday word for a digit on a hand; less formal than the technical term "digit".)

toe (Everyday word for a digit on a foot; used instead of the technical term in normal conversation.)
