The symbol "∑" is called the summation symbol. It is used to represent the sum of a series of numbers or terms. For example, the expression ∑n from n=1 to 5 would mean the sum of the numbers 1, 2, 3, 4, and 5.
The symbol "√" is called the radical symbol or square root symbol. It is used to indicate the square root of a number. For example, √25 would mean the square root of 25, which is 5.
The symbol "π" is called pi and is a mathematical constant. It is used to represent the ratio of a circle's circumference to its diameter. It is approximately equal to 3.14159.
The symbol "≤" is called the less than or equal to symbol. It is used to compare two numbers and indicates that the first number is less than or equal to the second number. For example, 2 ≤ 5 would mean that 2 is less than or equal to 5.
The symbol "∠" is called the angle symbol and is used in geometry to represent an angle. It is typically followed by three letters, such as ∠ABC, indicating the angle formed by the points A, B, and C. The angle is measured in degrees or radians.
