Scientific Calculator

The Scientific Calculator extends a basic four-function calculator with the advanced operations needed for algebra, trigonometry, and science coursework. Beyond add, subtract, multiply, and divide, it handles exponents and roots, logarithms (both base-10 and natural log), trigonometric functions like sine, cosine, and tangent, factorials, and constants such as pi and Euler's number. It evaluates expressions according to the standard order of operations so parentheses and powers resolve before multiplication and addition.

Internally it parses your typed expression, respects operator precedence (PEMDAS/BODMAS), and computes using floating-point math. Trigonometric functions depend on whether you are working in degrees or radians, which is the single most common source of wrong answers — make sure the angle mode matches your problem. Functions like square root, logarithm, and arcsine also have domain restrictions, so a negative input under a real square root or a log of a non-positive number will not produce a valid real result.

It suits students checking trig and logarithm homework, engineers running quick exponential or power calculations, and anyone needing precise constants without memorizing their digits. Because it follows order of operations, you can type a multi-step expression in one line rather than chaining intermediate results by hand. For purely whole-number base conversions you would reach for a tool like Hex to Decimal instead, and for exact fractional arithmetic the Fractions Calculator keeps results unrounded.

A practical tip: use parentheses liberally to make your intent unambiguous, since 1/2x can be read two different ways depending on a calculator's parsing rules. Also remember that factorials grow extremely fast and large exponents can exceed the precision of floating-point numbers, producing rounding at the far decimal places.
