What does this calculator estimate?
2 + 3 x 4 = 14 because multiplication happens before addition. The tool evaluates expressions following PEMDAS: parentheses, exponents, multiplication/division left to right, then addition/subtraction.
- PEMDAS order: parentheses, exponents, multiplication/division, addition/subtraction (Wikipedia).
- Multiplication and division share priority, evaluated left to right.
- 2 + 3 x 4 is 14, not 20.
Why order of operations matters
Math expressions are ambiguous without a fixed evaluation order — that's what PEMDAS defines. The same expression evaluated differently gives different answers (2 + 3 × 4 is 14, not 20). The calculator applies standard precedence.
Limitations to watch for
Multiplication and division share precedence, evaluated left to right — same for addition/subtraction. Implicit multiplication (2(3+4)) may parse differently across tools. Enter parentheses explicitly to remove ambiguity.
How to use it in practice
Type the expression with explicit parentheses for clarity. Use it to check homework, formulas, and spreadsheet logic. When sharing formulas, write them unambiguously — calculators and code both follow PEMDAS.

How this calculator works
Formula
Evaluates expressions following PEMDAS: parentheses, exponents, multiplication/division (left to right), addition/subtraction (left to right).
Worked example
2 + 3 × 4 = 14 — multiplication happens before addition.
Assumptions to verify
- Standard PEMDAS precedence applies.
- Multiplication/division and addition/subtraction are left-to-right.
- Parentheses are explicit where intended.
Frequently asked questions
What is PEMDAS?
Parentheses, Exponents, Multiplication/Division, Addition/Subtraction — the order math expressions are evaluated.
Why is 2 + 3 × 4 equal to 14?
Multiplication runs before addition: 3 × 4 = 12, then + 2 = 14.
Do multiplication and division share precedence?
Yes — left to right, same for addition and subtraction.
What about implicit multiplication?
2(3+4) is ambiguous — write 2 × (3+4) to be clear.
How do I get 20 from 2 + 3 × 4?
Add parentheses: (2 + 3) × 4 = 20.
Does it handle exponents?
Yes — the tool supports standard operators including exponents.
Why does it matter in code?
Programming languages follow the same precedence rules — knowing them prevents logic bugs.
