There were probably animal species that used addition even before the first humans appeared on the planet. Groups had to decide if their side had more or fewer members than an enemy group and so decide whether to fight or run.
The addition sign was first used in 1544.
Subtraction is used to check addition.
Multiplication comes before addition.
In mathematical operations, addition, subtraction, and multiplication are governed by the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). When addition, subtraction, and multiplication are used in a problem, multiplication is performed first, followed by addition and subtraction, which are executed from left to right. Thus, in a sequence where these operations appear together, multiplication takes priority over addition and subtraction.
The addition symbol was first used in 1544 by Michael Stiple. I do not know when the subtraction sign was first used, I'm still trying to find that out myself!
