In the equation "x + 2 = 5", x can only have a value of 3.The statement (the equation) is not true for any other value. Learn what variables are and practice using them in expressions. How to use variable in a sentence. See more. independent variable. variable [var´e-ah-b'l] something that changes; an attribute or property of a person, event, or object that is known to vary in a given study. Typically, we use a single letter to represent a variable. Independent variables represent the “input” value of a function, and are commonly denoted as x. a math process (like adding, subtracting, multiplying, or dividing) algebraic expression an expression that contains a variable, a number and at least one operation symbol Definition Of Variable. A dependent variable is determined by another variable. In this context (that is, when the variable "holds" a fixed value that you can find by solving), the variable may also be called "the unknown".
adj. Variable definition is - able or apt to vary : subject to variation or changes. That is, the estimation of the word variable is dependably said to be reliant on the free variable of math condition. An independent variable is not influenced by another variable. When a variable is used in an function , we know that it is not just one constant number, but that it can represent many numbers. A defining variable is a symbol, such as x, used to describe any number. Likely to change or vary; subject to variation; changeable. The dependent variable is characterized as the variable whose quality depends on the estimation of another variable in its condition.
For instance, consider the condition y = 4x + 3.

The following are examples of algebraic expressions and equations containing variables.
That is to say, the value of x is "fixed"; we just have to figure out what that fixed value is. Variables are (usually) letters or other symbols that represent unknown numbers or values. Variable (mathematics) synonyms, Variable (mathematics) pronunciation, Variable (mathematics) translation, English dictionary definition of Variable (mathematics). A variable is a quantity that takes different values in different situations or conditions. In general we use alphabets like x,y, z p,q,r,... to denote a variable quantity.
The major concepts covered in these tutorials are substitution, the distributive property, and combining like terms. They are sometimes called the “argument” of the function.
2x + 5 = 10, the variable here is x 7y + 10 = 24, the variable here is y a 2 + b 2, the variables here are a and b Variables are used throughout math after Algebra, and are important to understand. A variable is a quantity that may change within the context of a mathematical problem or experiment.
