About this calculator
Without a fixed order, 2 + 3 × 4 could mean 20 or 14. PEMDAS resolves that: multiply before add, so the answer is 14. Parentheses override everything inside them first.
Type an expression using digits, +, −, *, /, ^, and parentheses. The calculator parses and evaluates left-to-right within each precedence level.
Use it to check homework, settle calculator disputes, or sanity-test spreadsheet formulas. For step-by-step long division try the [[long-division]] calculator. For powers alone use the [[exponent]] calculator. For a full keypad see the [[math-calculator]].
Common uses
- Verify PEMDAS homework answers
- Evaluate nested formulas quickly
- Check whether parentheses change the result
- Test simple expressions before coding them
Frequently asked questions
What is 2 + 3 × 4?
14. Multiplication comes before addition: 3 × 4 = 12, then 2 + 12 = 14. Writing (2 + 3) × 4 would give 20.
Does this follow PEMDAS or BODMAS?
Same order — parentheses/brackets, orders/exponents, division and multiplication left to right, addition and subtraction left to right.
Can I use exponents?
Yes. Use ^ for powers, e.g. (2+3)^2 = 25. Exponentiation binds tighter than multiply and add.
What characters are allowed?
Digits, decimal points, +, −, *, /, ^, and parentheses. Spaces are ignored.
