# What is an equal expression?

**expressions**are

**expressions**that are the same, even though they may look a little different. If you plug in the same variable value into equivalent

**expressions**, they will each give you the same value when you simplify.

Beside this, what is an example of an equivalent expression?

**Examples** of **Equivalent Expressions** 3x+2 and 3x + 6 are **equivalent expressions**, because the value of both the **expressions** remains same for any value of x. For instance, for x = 4, 3x+2 = 34+2 = 18 and. 3x + 6 = 3 x 4 + 6 = 18.

Likewise, what is a numerical expression? **Numerical Expression** Definition. A **numerical expression** is a mathematical sentence involving only numbers and one or more operation symbols. Examples of operation symbols are the ones for addition, subtraction, multiplication, and division.

Similarly, what is a defined expression?

An **expression** is a sentence with a minimum of two numbers and at least one math operation. This math operation can be addition, subtraction, multiplication, and division.

How do you write an expression in math?

An **example** of a **mathematical expression** with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the **expression** 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.
