What does this symbol x mean in math?
variable
The letter “x” is often used in algebra to mean a value that is not yet known. It is called a “variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol. See: Variable.
What does [[ x ]] mean?
IN MATH: 1. n. the function, or rule which produces the “greatest integer less than or equal to the number” operated upon, symbol [x] or sometimes [[x]]. The greatest integer function is a piece-wise defined function.
What is the value of x?
To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
What are functions of X?
The phrase “y is a function of x” means that the value of y depends upon the value of x, so: y can be written in terms of x (e.g. y = 3x ). If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x”s by 4″s .
What is the first step to solve for x?
The first step to solving for x is going to be getting x alone on one side of the equation and everything else on the other side. Remember the algebraic golden rule: What you do to one side of the equation, you must do to the other side. That’s how the equation stays equal!
What is X into X?
In algebra, x multiplied by x can be written as (x) × (x) or x . x (or) x2. So, x squared = x2.
How do you make X by itself?
Getting x by itself depends on the particular question. Usually you will want to combine like terms and then cancel, but there are many different possibilities. Generally, think of what is being done to x and then “undo” it by doing the opposite, and do that on both sides of the equal sign.

What is x2 algebra?
x squared is a notation that is used to represent the expression x×x x × x . i.e., x squared equals x multiplied by itself. x squared symbol is x2 .
