Understanding Expression Evaluation

An expression evaluator is a tool that calculates the numerical value of a mathematical expression. It interprets the expression based on standard mathematical rules and order of operations (like PEMDAS/BODMAS).

Order of Operations (PEMDAS/BODMAS):

• Parentheses / Brackets: Operations inside parentheses or brackets are performed first. Example: (2 + 3) * 4
• Exponents / Orders: Exponents and roots are evaluated next. Example: 2^3 + 9
• Multiplication and Division: These operations are performed from left to right. Example: 10 / 2 * 3
• Addition and Subtraction: These operations are performed from left to right. Example: 8 - 4 + 2

Example Expressions:

• 2 + 3 * 4 (Result: 14, Multiplication before addition)
• (10 - 2) / 2 (Result: 4, Parentheses first)
• 5^2 - 10 (Result: 15, Exponent before subtraction)
• sqrt(25) + 7 (Result: 12, Square root before addition)

Use this tool to quickly evaluate any mathematical expression, whether simple or complex, and understand the step-by-step calculation process.
