- Exponent CalculatorLaws of exponentsAn exponent is repeated multiplication, and everything else about exponents follows from keeping that idea consistent. This…
- Square Root CalculatorPrincipal square root; Newton–Raphson iterationThe square root of a number is the value that, multiplied by itself, gives that number back. This calculator returns the…
- Logarithm CalculatorChange-of-base identityA logarithm answers one question: what power do I raise this base to in order to get this number? Enter a value and a base and…
- Scientific Notation CalculatorSI conventions, NIST SP 811Scientific notation writes any number as a coefficient between 1 and 10 multiplied by a power of ten, so 93,000,000 becomes 9.3…

Which one do you need?
- Exponent Calculator
- Raise any base to a whole, negative or fractional exponent. See the expanded multiplication, the reciprocal and the result in scientific notation.
- Square Root Calculator
- Find the principal square root of any number, check whether it is a perfect square, see the nearest squares either side, and follow the Newton iteration.
- Logarithm Calculator
- Evaluate log base b of x with the change-of-base formula, plus the natural log, log base 2, log base 10, and the antilog that reverses them all.
- Scientific Notation Calculator
- Convert any number to scientific, E or engineering notation and back, and multiply, divide, add or subtract two values with the exponents handled for you.
- Exponential Growth & Decay Calculator
- Project a quantity forward or backward under an exponential model and convert between percent rate, continuous rate k, doubling time and half-life.
