What is a plus?

The very first book in which the plus symbol was used is considered a commercial treatise developed by Johann Widman. In this work, the symbol was used as a sign of increasing. Already in the sixteenth century, plus is found in the books of Viet and other mathematicians. The creator of an algebraic language of symbols often used a plus to denote a basic action — addition. Let us consider in more detail what is a plus.

Plus is:

  • comparative;
  • graphic symbol that denotes the operation of addition;
  • positive number symbol;
  • a sign indicating a school mark increase;
  • the sign used to indicate temperature;
  • positive side or dignity;
  • benefit or advantage.
