Unlock the power of numbers with our comprehensive suite of free online math calculators. From basic arithmetic to advanced calculus, solve complex problems, understand concepts, and get instant, accurate results for all your academic, professional, and everyday math challenges.
For functions like sin(30), enter: Math.sin(30 * Math.PI / 180).
Choose a sub-category:
Perform matrix operations such as addition, subtraction, multiplication, transpose, determinant, inverse (for 2x2), and scalar multiplication.
The scratchpad is a space for you to jot down temporary numbers or notes as you perform calculations across different calculators.
For functions like sine (sin), cosine (cos), and tangent (tan), use the buttons provided. Angles should be entered in degrees. For example, to calculate sin(30), press 'sin', then enter '30', and finally '='.
Enter fractions using the '/' symbol. For example, one-half would be '1/2'. You can perform operations like addition, subtraction, multiplication, and division between fractions (e.g., '1/2 + 3/4').
You need to input two values: the 'Experimental Value' (the value you measured) and the 'True Value' (the accepted or correct value). The calculator will then determine the percentage error.
Enter the 'Base' number and the 'Exponent' (the power you want to raise the base to). Click 'Calculate' to get the result.
These are the coefficients of the quadratic equation in the standard form \(ax^2 + bx + c = 0\). Enter the numerical values for a, b, and c to find the roots of the equation.
First, select the statistical calculation you want to perform (e.g., 'Mean', 'Median', 'Standard Deviation'). Then, enter the dataset (usually comma-separated numbers) in the input field provided and click 'Calculate'.
Enter the two numbers you want to analyze in the designated input fields. After clicking 'Calculate', the calculator will display both the Least Common Multiple (LCM) and the Greatest Common Factor (GCF) of those numbers.
Go to the 'Geometric' calculator, select the 'Area' calculation type, then choose 'Circle'. Enter the radius of the circle in the input field, and click 'Calculate'. The result will show the area.
The Scratchpad is a temporary note-taking area. You can type in numbers or any text you need to remember while using the different calculators on this page. It's like a piece of paper next to your physical calculator.
