Plus and minus signs

The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference.^[1] Their use has been extended to many other meanings, more or less analogous. Plus and minus are Latin terms meaning "more" and "less", respectively.

The forms ⟨+⟩ and ⟨−⟩ are used in many countries around the word. Other designs include ⟨﬩⟩ for plus and ⟨⁒⟩ for minus.
