This scientific calculator parses your entire expression and evaluates it with proper precedence — parentheses first, then exponents and roots, then multiplication and division, then addition and subtraction. Trigonometric functions respect the Deg/Rad switch, and the memory keys let you store a running value.
Scientific Calculator
A full scientific calculator with trigonometry, logarithms, powers, roots and memory.
How it works
Evaluates full expressions with correct operator precedence (PEMDAS), in degrees or radians.
Frequently asked questions
Does it use degrees or radians?
Both — toggle Deg/Rad at the top and the trig functions follow the selected mode.
How do I calculate a root?
Use √x for square root, ³√x for cube root, or the index then ʸ√x then the number for any root.
