## Is 3x a variable expression?

A term is a single mathematical expression. Examples of single terms: 3x is a single term. The “3” is a coefficient. The “x” is the variable.

**How would you write 3 times a number?**

Three times a number is represented by 3n . Plus 8 is obvious. “Is” is equivalent to writing “equals”.

### What is a number multiplied by a variable?

A coefficient is a number multiplied by a variable. Examples of coefficients: In the term g, the coefficient is 1.

**What is mathematical expression example?**

In algebra, we begin to see variables, or letters that are used to represent numbers. An example of a mathematical expression with a variable is 2x + 3. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.

## How do you write an expression?

How do you Write an Expression? We write an expression by using numbers or variables and mathematical operators which are addition, subtraction, multiplication, and division. For example, the expression of the mathematical statement “4 added to 2”, will be 2+4.

**What number is thrice?**

three times, as in succession; on three occasions or in three ways.

### How do you write a math expression?

**What does 3 times a number mean?**

Explanation: let the number be n. then ‘3 times the number’ means the number multiplied by 3. ie 3×n=3n.

## What is one third of a number?

Thirds are calculated by dividing by 3. For example: One third of 24 =1/3 of 24 = 24/3 = 8.

**How do you multiply expressions with variables?**

To multiply terms, multiply the coefficients and add the exponents on each variable. The number of terms in the product will be equal to the product of the number of terms.

### What is a number that is multiplied by the variable in an algebraic expression where the number is a decimal?

A coefficient can be positive or negative, real or imaginary, or in the form of decimals or fractions. Another definition of coefficient says, “Any number with which we multiply a variable.” For example, in the term 9.3x, 9.3 is the coefficient of the variable x, and in -5z, -5 is the coefficient.
