# What is the use of order in numerical expressions?

In a mathematical sentence, the term numerical expression involves only numbers and operation symbols like addition, subtraction, multiplication, and division.

## Answer: The use of order in numerical expressions is very useful to specify the sequence in which the numerical operations can be performed and it gives the way to get the correct answer for any given numerical expression.

Order is useful to find the correct answer for any given numerical expression.

**Explanation:**

Few steps used for the order in numerical expressions.

- First, we solve the operations inside the brackets symbols.
- Second, we simplify the powers.
- Third, from left to right we solve multiplication and division.
- Fourth, we go for addition and subtraction from left to right.

Hence, there are multiple operations involved in a numerical expression and we can say that the order for solving numerical expressions is:

Parentheses, Division, Multiplication, Addition, and Subtraction.

For example,

25 - [4 + {26 - (28 - 8}]

Solution:

25 - [4 + {26 - (28 - 8}]

= 25 – [4 + {26 – 20}] Subtract 8 from 28 and remove the parenthesis.

= 25 – [4 + 6] Subtract 20 from 26 and remove the curly brackets.

= 25 – 10 Add 4 and 6 and remove the brackets.

= 15 and in the last step subtract 10 from 25
