…

A term is a single number, variable, or a number and a variable multiplied together.

A variable expression is a combination of terms and mathematical operations that contains at least one variable..

## How do you define a variable and write an algebraic expression?

Summary: A variable is a symbol used to represent a number in an expression or an equation. The value of this number can change. An algebraic expression is a mathematical expression that consists of variables, numbers and operations. The value of this expression can change.

## What type of variable is time?

Continuous variableContinuous variable: a variable with infinite number of values, like “time” or “weight”.

## What are different forms of expression?

## Whats is variable?

A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

## What are the 3 types of variables in research?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

## What type of variable is income?

Continuous Variables A continuous variable can take on any score or value within a measurement scale. In addition, the difference between each of the values has a real meaning. Familiar types of continuous variables are income, temperature, height, weight, and distance.

## What is an expression write an example?

Numbers, symbols and operators (such as + and ×) grouped together that show the value of something. Examples: • 2 + 3 is an expression.

## What are 3 types of variables?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.

## What is a basic expression?

BASIC Expression: An expression can be variable or constant or combination of them. Operator: An operator is a symbol or sign that specifies the certain operation to be carried out with given data or operand. For example c= a + b, where ‘=’ and ‘+’ are operators. … and finally returns either true or false value.

## How do you use variable in a sentence?

## What is variable and its types?

Variables represents the measurable traits that can change over the course of a scientific experiment. In all there are six basic variable types: dependent, independent, intervening, moderator, controlled and extraneous variables.

## Which is an example of variable terms?

A symbol for a value we don’t know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable. Why “variable” when it may have just one value?

## What are terms in a expression?

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

## What is the value of an expression?

The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the quantity assumed by the function for these argument values.
