What it does
Type an equation the way you would write it on paper and Equations Calculator finds the answer, explains each step, and draws a graph so you can see where the answer comes from. It handles simple equations, squares and higher powers, fractions, square roots, exponentials, logarithms, trigonometry, and several equations solved together.
Why we built it
Many calculators give an answer and nothing else. We wanted one that helps you understand the answer: exact fractions and square roots where they exist, clear working, and honest messages when an equation has no answer or can't be solved.
How we keep answers correct
- Every answer is checked by putting it back into your equation before it is shown.
- When the calculator can't be sure, it says so instead of guessing.
- It is tested against thousands of equations with known answers.
Your privacy
Everything is calculated in your own browser. Your equations are never sent to us or anyone else. See the Privacy Policy for details.
