Numerical Expression – Definition, Example and Simplification

Introduction to Numerical Expression

A numerical expression is a mathematical statement that contains one or more variables and numbers. The variables in a numerical expression can be replaced by numbers in order to solve the equation. In most cases, the numerical expression will be an equation that needs to be solved. Numerical Expression – Definition Example and Simplification.

What is the Meaning of Numerical?

Numerical is the meaning of a number or quantity. It is a number that is used to represent a quantity, such as a measurement or a count.

Numerical Expression Example

A numerical expression is an algebraic expression that is composed of numbers and variables, and it is evaluated by substituting specific values for the variables. For example, the numerical expression 4x + 7 can be evaluated by substituting the value 4 for the variable x and the value 7 for the variable y. In this case, the numerical expression would evaluate to the value 21.

How to Write Numerical Expression?

Numerical expressions are mathematical equations that use numbers and operations. The most basic numerical expression is a number, such as 5. You can also use operators, such as + (addition), – (subtraction), * (multiplication), and / (division), to create more complex expressions. For example, the numerical expression 5 + 3 is 7.

Simplification of Numerical Expressions

In order to simplify a numerical expression, one can combine like terms. For example, the numerical expression

3x + 5x

can be simplified to

8x

Simplify the Following Numerical Expressions

1. (2x + 1) + (3x – 2)

2x + 2

2. (x + 1)2

x2 + 2x + 1

3. (3x + 2) ÷ (x – 1)

3x + 2

x + 1

4. (4x – 1)2

16×2 – 4x + 1
