Math is comprised of primarily two things: numbers and symbols. Symbols are found in simple math, algebra, geometry, calculus, statistics, etc. Symbols are essentially representative of a value. Decimals and fractions, for example, are symbols of parts of a whole. These symbols allow us to "work with" parts in a theoretical manner.
Feb 1, 2011 · 64 + 23 - 5 = 87 - 5 = 82. Someone, often long ago, invented these symbols and other people started using them. The plus sign + seems to have started as a quick way of writing the Latin word et, which means 'and' as long ago as the year 1417. Here is a picture of some of the earliest uses of plus + and minus - symbols in a printed book (1526).

The development of mathematical notation was intimately bound up with the general evolution of mathematical concepts and methods.
Mathematical symbols for an unknown quantity and its powers were highly diverse. During the 16th century and early 17th century, more than ten rival notations were current for just one square of an unknown; among these were ce (from census — the Latin term serving as translation for the Greek term $\delta \upsilon'\nu\alpha\mu \iota\varsigma$), Q (...
The further development of mathematical symbols was intimately connected with the invention of infinitesimal calculus, though the basis had already been prepared to a considerable extent in algebra. I. Newton, in his method of fluxions and fluents (1666 and later), introduced symbols for successive fluxions (derivatives) of a quantity $x$: $\dot{x}...
During the 19th century, the role of notation became even more important; as new fields of mathematics were opened up, scholars endeavored to standardize the basic symbols. Some widely employed modern symbols appeared only at that time: the absolute value $|x|$ (K. Weierstrass, 1841), the vector $\vec{v}$ (A. Cauchy, 1853), the determinant\[\left|\...
From the point of view of mathematical logic, mathematical symbols can be classified under the following main headings: A) symbols for objects, B) symbols for operations, C) symbols for relations. For example, the symbols 1, 2, 3, 4 denote numbers, i.e., the objects studied in arithmetic. The symbol for the addition operation, $+$, standing on its ...

Mar 12, 2024 · Common mathematical symbols are the building blocks of all mathematical functions. Bankrx/Shutterstock. Key Takeaways. The 11 basic symbols essential for writing mathematical equations are the plus (+), minus (-), equals (=), does not equal (≠), multiplication (×), division (÷), greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), fraction ...

In mathematics and logic, the “and” symbol is represented by ∧ and the “or” symbol by ∨. Here’s a simple example using these symbols: Example 1: Statement: “It is raining and cold.”. Mathematical Expression: Let statement p represent “It is raining” and q represent “It is cold.”. The expression becomes p∧q.
