An arithmetic expression contains operators and operands, along with constants and operations. It can take three forms: prefix, infix, or postfix. In prefix form, the operator comes before the operands. In infix form, the operator is between the operands. And in postfix form, the operator follows the operands. The main advantages of arithmetic expressions are that they are easier to evaluate, require fewer brackets, and are fast to calculate. However, they are sensitive to extreme values and not suitable for time series data.

Arithmetic Expression

2. DEFINITION OF ARITHMETIC EXPRESSION:
Arithmetic Expression is a expression having ope
-rators and operands. Also Arithmetic Expression
involves constants and operations.
Arithmetic Expression or Polish Notation is of 3
Types :-
1. Prefix
2. Infix
3. Postfix

3. • Infix: When the operator is placed between its 2
operands, the expression is in Infix form.
Example: a+b
• Prefix: When the operator is placed before its 2
operands, the expression is in Prefix form.
Example: +ab
• Postfix: When the operator is placed after its 2
operand's, the expression is in Postfix form.
Example: ab+

5. Advantages:
• Easier to evaluate an expression
• Less overhead of brackets
• Fast and easy to calculate
• Easy to work with and use in further analysis
Disadvantage:
• Sensitive to extreme values
• Not suitable for time series type of data
• Works only when all values are equally important
