Mathematics uses a wide range of symbols to represent concepts, operations, and relationships. Some commonly used math symbols include:
1. Plus (+) and Minus (-): The plus symbol represents addition, while the minus symbol represents subtraction. They are used to combine or separate quantities.
2. Multiplication (×) and Division (÷): The multiplication symbol denotes multiplication, and the division symbol represents division. They are used to perform these operations on numbers or variables.
3. Equality (=): The equality symbol indicates that two quantities are equal. It is used to express equations and compare values.
4. Greater Than (>) and Less Than (<): These symbols are used to compare the relative size or magnitude of two quantities. Greater than indicates that one value is larger, while less than indicates that one value is smaller.
5. Summation (∑): The summation symbol represents the sum of a series of numbers or terms. It is used in mathematical notation to express the total value obtained by adding all the terms together.
6. Pi (π): Pi is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is approximately equal to 3.14159 and is used in various mathematical formulas.
