They are used to simplify expressions by helping to reduce the numbers that there is

Replace the variables with the correct values and calculate using the order of operations
If you change the order of operations, you will get a different result. The person who wrote the expression had a specific order of operations in mind (using generally-accepted rules), so arbitrarily using some other order of operations is, quite simply, wrong.
They both use PEMDAS or Order of Operation
To Evaluate expressions using the order of operations where there are fraction bars, simplify the top and bottom first, then divide.
Order of Operations
Many expressions involve two or more operations. When simplifying such expressions, it is important to perform the operations in the following order:1. Perform any operation(s) within group symbols, which are:a. parentheses ( )b. brackets [ ]c. braces { }d. fraction bar /e. absolute-values bar | |f. radical sign2. Simplify all powers.3. Multiply and divide in order from left to right.4. Add and subtract in order from left to right.If you don't follow this order of operations, you will find a wrong answer.
Inverse operations are used to undo mathematical operations and isolate a variable. They help to solve equations and simplify expressions by moving operations to the opposite side of the equation. This allows us to find the value of the variable that makes the equation true.
order of operations
You cannot usually simplify numbers. What you can simplify is numeric or algebraic expressions. You carry out the various operations but use BODMAS (I prefer BIDMAS) to determine the order. First do the Brackets. Next the Index (or power Of) Then, with equal priority, Division and Multiplication And last, again with equal priority, Addition and Subtraction.
The standard order of operations follows the acronym PEMDAS. This is Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So operations are done on expressions within parentheses first.
order of operations
Replace the variables with the given values. Then you calculate using the order of operations.
Math can be difficult at times. To simplify a math expression, it is important to follow the order of operations, or PEMDAS.
Using pemdas / gema
The various operations within the expression are carried out using the order of operations: BIDMAS (UK) or PEMDAS (US).
