# How to Spell Numbers

Spelling Negative Numbers

A minus sign in writing becomes the word negative (formal, mathematical) or minus (casual) in speech.

Rules

  1. Negative is the formal word, used in math, science, and finance.
  2. Minus is common in speech and in temperature readings (minus ten degrees).
  3. Don't use both: negative minus five is wrong.
  4. Accountants sometimes write negatives in parentheses instead: ($1,450) means negative one thousand four hundred fifty dollars.
