The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, the symbol + represents the operation of addition, which results in a sum, while the symbol − represents subtraction, resulting in a difference. [1]
Representing the operation of addition, the + symbol indicates the process of combining two or more quantities. It's an essential building block of arithmetic and foundational to more advanced mathematical concepts.
The word plus means “more” in Latin, and minus means “less.” Although hieroglyphics existed in early Egyptian times to symbolize addition, it is not clear whether these symbols became the basis for today’s plus sign. The earliest known use was in Nicole Oresme’s manuscripts in the 14th century B.C.E.
The plus sign, also known as the plus symbol, isn’t only a representation of addition or positive numbers in mathematics. Its symbolism extends far beyond these mathematical applications, permeating various cultural, spiritual, and practical contexts.
A plus sign is the sign + which is put between two numbers in order to show that the second number is being added to the first. It can also be put before a number to show that the number is greater than zero (+3), and after a number to indicate a number that is more than a minimum number or amount (18+).
The plus sign (+) means "ADD" in programming and on calculator keyboards. For example, 10 + 7 means 10 added to 7. It is also used as a concatenation symbol for text fields.
The apartment isn't perfect, but the fact that it has new appliances is a plus. The state college's low tuition is only one of its pluses. [= advantages, benefits] The job doesn't pay well, but the convenient hours are a definite plus.
