The symbol of addition, known as "simbolo de suma" in Spain, is a fundamental element in mathematics that allows us to combine or add quantities together. This article will delve into the history, usage, and interesting facts about this essential mathematical symbol.
History of the Addition Symbol
The addition symbol (+) has been in use since the 14th century, with its earliest known appearance in the work of the French mathematician Nicole Oresme. However, it wasn't until the 16th century that it gained widespread acceptance and use. The symbol is believed to have evolved from the Latin word "et," which means "and."
Usage of the Addition Symbol
The addition symbol is used to indicate that two or more numbers should be combined to find their total. For example, 2 + 3 means "2 and 3," and the result is 5. It's important to note that the order of operations (PEMDAS/BODMAS) dictates that addition should be performed before subtraction, multiplication, and division.

The addition symbol is one of the most recognizable symbols in the world. It's so ubiquitous that it's often used in everyday language to indicate agreement or support, as in "I'm +1 for that idea."
