##### Infix notation is a way of writing arithmetic expressions in which the operands (numbers) are written between the operator symbols. For example, the infix expression “2 + 3” means “add 2 and 3.”

On the other hand, postfix notation is a way of writing arithmetic expressions in which the operands are written after the operator symbols. The same expression “2 + 3” would be written as “2 3 +” in postfix notation.

Are you one who finds converting infix to postfix expressions confusing? Understandably so, as it’s not always easy to manually convert an expression from one form to another without introducing mistakes. Worry not for there is a perfect solution for this- an Infix to Postfix online converter.

An infix to postfix calculator or converter is an online tool created to convert an infix expression (x+y*z) to its postfix form (xyz*+). It is a useful tool that reduces the time for solving mathematical equations that involve a lot of calculations.

The algorithm used for the conversion is called the Shunting Yard algorithm which was invented by the famous computer scientist Edsger Dijkstra. This algorithm stores the operators in one stack and the operands in another stack and then moves them across as it identifies them. This algorithm can also be used to detect errors in infix expressions easily.

Infix to Postfix converters are usually created in programming languages such as C and C++. The code looks complex and non-intuitive and requires some trial and error to reach the final solution. Therefore, it can be difficult or intimidating for some to write the code.

Infix to Postfix online converters help those who are short of time or ideas to quickly convert their infix expressions to postfix expressions. It is also useful for those who have no access to coding programs.

In conclusion, infix to postfix converters help anyone who is struggling with manually converting an expression from one form to another with accuracy and ease. It is a useful tool solve complex equations and is accessible to everyone with a computer and an internet connection. You can also try our postfix to Infix online converter tool

## To convert an infix expression to postfix notation, you can use the following steps:

- Create an empty stack
- Start scanning the infix expression from left to right
- If the current character is an operand, append it to the result string
- If the current character is an operator, push it onto the stack
- If the current character is a left parentheses, push it onto the stack
- If the current character is a right parentheses, pop operators from the stack and append them to the result string until you reach a left parentheses. Discard the left and right parentheses.
- Repeat steps 2-6 until you have scanned the entire expression
- Pop any remaining operators from the stack and append them to the result string
