📘 About the Scientific Calculator

A scientific calculator handles everything beyond + − × ÷: powers and roots, trigonometric functions, logarithms, factorials and constants like π and e. It follows the order of operations (BODMAS/PEMDAS), so 2 + 3 × 4 = 14.

Type the whole expression in one line. The answer is shown to 12 significant figures, with the exact fraction or surd when there is one, scientific notation, and binary, octal and hexadecimal for whole numbers. Choose degrees or radians for trigonometry.

🧮 Formula

Order of operations

Brackets → powers → × ÷ → + −

Logs

log(x) = log₁₀ x, ln(x) = logₑ x, log(x, b) = log_b x

Factorial

n! = 1 × 2 × … × n

❓ Frequently asked questions

What is sin 30°?

0.5 in degrees mode. In radians, sin(30) ≈ −0.988 — always check the angle mode.

How do I type a square root or cube root?

sqrt(x) or √x for square roots, cbrt(x) or x^(1/3) for cube roots, and x^(1/n) for any root.

What is the difference between log and ln?

log is base 10 (log 1000 = 3), ln is the natural log, base e (ln e² = 2).
