Did this calculation save you time?
Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.
I keep this website 100% free, private, and ad-free. If this helped you with your homework, project, or finances today, bookmarking this page or telling a friend helps me keep building more free tools!
The Best Scientific Calculator is an advanced online computing tool supporting higher mathematical, scientific, and engineering calculations including trigonometry in degrees and radians, exponential and logarithmic functions, factorials, and memory registers.
\sin(\theta), \quad \cos(\theta), \quad \ln(x) = \log_e(x), \quad x^y = e^{y \ln x}, \quad n! = \prod_{k=1}^n kSupports complete IEEE 754 floating-point arithmetic with domain-checked trigonometric and logarithmic operations.
Scenario: Evaluating sin(30°) + ln(e) + 5!
sin(30°) in DEG mode = 0.5
ln(e) = 1.0
5! = 5 × 4 × 3 × 2 × 1 = 120
Sum: 0.5 + 1.0 + 120 = 121.5
Use Degrees (DEG) for high school geometry, navigation, surveying, and physics problems specifying angles in degrees. Use Radians (RAD) for calculus, advanced physics, and periodic wave analysis.
log (or log10) is the common logarithm with base 10 (e.g., log(100) = 2). ln is the natural logarithm with base e ≈ 2.71828 (e.g., ln(e) = 1).
By mathematical definition, 0! = 1, reflecting the fact that there is exactly one way to arrange zero objects.
Yes! The calculator supports standard keyboard input for digits, operators (+, -, *, /), parentheses, and Enter for equals.
Calculate the principal real cube root of positive and negative numbers. Identifies perfect cubes, nearest integer roots, and complex conjugate roots.
Solve linear equations (ax+b=0), quadratic equations (ax²+bx+c=0 with discriminant Δ and complex roots), and 2x2 systems with step-by-step solutions.
Decompose rational functions P(x)/Q(x) into partial fractions with linear and repeated roots using Heaviside’s cover-up method for calculus integration.
