Online Scientific Calculator

Try this scientific calculator for students who need to work with powers, roots, trigonometric, exponential and logarithmic functions. Find Least Common Multiple (LCM) and Greatest Common Divisor (GCD). Decomposes numbers into Prime Factor Product, finds the Divisors of a Number and the Remainder of the Euclidean Division. Functions do not need parentheses. It offers the option to perform arithmetic operations automatically or not, and the option to work with the mouse, keyboard or a combination.
Examples of how to use the Calculator

We'll give some examples of how the keys work and what each one does. Note that the functions don't need parentheses.
