an equation
It is an algebraic expression, if there are numbers and variables. For example: 2x + 2 = 4x(7-5) 20-29 = -9/3x If there are ONLY numbers and NO variables, it is called an arithmetic expression. For example: 3+3+3+3 = 4+4+4 2+6 = 4+4
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
That's eight letters, so: 8! = 40320 different arrangements. n! means "factorial", and the expression expands to n*(n - 1)*(n - 2) ... * 2 * 1
An angle cannot be formed by only one ray. However, an angle formed by two opposite rays is called a straight angle.

A mathematical expression is a finite combination of symbols which are well-formed in accordance with rules that depend on the context.
A sentence formed using words and mathematical symbols which is either true or false but not both.
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context. Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine the order of operations, and other aspects of logical syntax. Many authors distinguish an expression from a formula, the former denoting a mathematical object, and the latter denoting a statement about mathematical objects. For example, 8x-5 is an expression, while is a formula. However, in modern mathematics, and in particular in computer algebra, formulas are viewed as expressions that can be evaluated to true or false, depending on the values that are given to the variables occurring in the expressions. For example takes the value false if x is given a value less than –1, and the value true otherwise.
You are probably referring to an "equal to" sign (=). This sign makes one side of the equation equal to the other.
The expression "suppose to" isn't correct. It should be "supposed to"
A mathematical sentence that includes an equal sign between two expressions is called an equation. For example, in the equation (3x + 5 = 20), the left side (3x + 5) and the right side (20) are two expressions that are stated to be equal. Equations can be simple or complex and are fundamental in algebra for solving for unknown values.
"X plus 2" refers to the mathematical expression formed by adding the number 2 to a variable represented by "x." In this context, "x" can be any number, and the expression signifies the sum of that number and 2. It is often used in algebraic equations to solve for the value of "x."
Algebraic expressions are formed by combining numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. A variable represents an unknown value and is typically denoted by letters like x or y. For example, the expression 3x + 5 represents three times a variable x plus five. The structure of these expressions allows for the representation of mathematical relationships and the solving of equations.
