Which term best matches 'A whole number, positive or negative, that does not contain a decimal point and that is not written as a fraction'?

• A. Module
• B. Integer
• C. Float
• D. Index Number

Answer: (B)

A whole number with no decimal part and not written as a fraction is called an integer. It can be positive, negative, or zero. This distinguishes it from numbers with decimals or fractions, which are called floats. The other terms aren’t used to name this basic category of numbers in math—module isn’t a standard numeric type, and index number isn’t a common term for a numeric value. So the best fit is integer.
