Numerical expression

A numerical expression is a combination of numbers and mathematical operations such as addition, subtraction, multiplication, and division

A numerical expression is a combination of numbers and mathematical operations such as addition, subtraction, multiplication, and division. It does not contain variables or unknowns. Numerical expressions can be as simple as a single number, such as 12 or 3, and they can also be more complex, involving multiple operations and parentheses. For example, the expression 4 + (6 × 2) is a numerical expression.

Numerical expressions are used to perform mathematical calculations and represent the value of those calculations. They can be evaluated by following the order of operations, which dictates the sequence in which the operations should be performed. In the example above, the multiplication inside the parentheses is done first, resulting in 12. Then, the addition is carried out, resulting in a final value of 16.

Numerical expressions are commonly used in everyday life, such as calculating the total cost of items in a shopping cart, determining the distance traveled in a given amount of time, or finding the average of a set of numbers. They provide a concise and precise way of representing mathematical calculations.
