Free math solver for students. Just type naturally.

The best math solver for students doesn't make you learn special syntax first. Type your problem the way you'd say it out loud — Zeretis understands natural language and gives you a full step-by-step solution.

🛡️ Safe and private by design. Zeretis only responds to math. It can't go off-topic, won't generate anything harmful, and collects no personal data. A free account is required to track your usage.
Zeretis Solver
You type (plain English) what is the derivative of x squared plus 3x → f'(x) = 2x + 3
Step 1 — power rule on x² d/dx(x²) = 2x
Step 2 — power rule on 3x d/dx(3x) = 3
Step 3 — sum rule f'(x) = 2x + 3 ✓

No special syntax. Just say what you mean.

Most math tools require you to learn their input format before you can even start. Zeretis accepts plain English descriptions, standard notation, and LaTeX — all interchangeably. Use whichever feels most natural.

Yousolve x squared minus 5x plus 6 equals 0
Answerx = 2, x = 3 — full factoring steps shown

Youwhat is the integral of sin x from 0 to pi
Answer2 — antiderivative found, limits evaluated step by step

Youfind the slope of y = 3x² + 2x at x = 4
Answer26 — derivative computed symbolically then evaluated

You can also use standard notation (x^2 - 5x + 6 = 0) or LaTeX (\int_0^\pi \sin x\,dx). All three work. Switch freely between them in the same session.

From middle school to university level.

The solver handles the full range of math you'll encounter as a student — from basic algebra through to university-level calculus and differential equations.

More than just an answer.

Seeing the answer isn't enough to pass an exam — you need to understand the method. Zeretis shows every step so you can follow the reasoning, spot where your own working went wrong, and actually learn how the math works.

📋

Full step-by-step working

Every solution shows each transformation applied, with the rule used at that stage labelled clearly. You see the method, not just the result — exactly like a textbook worked example, for any problem you enter.

Check your own working

Entered your own solution? Compare it step-by-step with the solver's output. See exactly where a mistake crept in — before your teacher sees it.

🔁

Consistent, reliable results

Zeretis uses deterministic symbolic computation, not AI. The same problem always gives the same result. No guessing, no approximation errors, no hallucinated steps.

🔒

Private & safe to use

No personal data collected. The solver only responds to math — it can't be used to access inappropriate content or go off-topic. Safe for use at school or at home.

📱

Works on any device

Phone, tablet, or laptop — fully mobile-friendly. Do your homework at the kitchen table, on the bus, or anywhere else without installing anything.

💸

Free to start

10 problems a month at no cost, no credit card needed. Upgrade to unlimited for less than a coffee per week when you need more.

Three steps to any solution.

1

Type your problem — any way you like

Write it in plain English ("what is the derivative of x cubed"), standard notation (x^3), or LaTeX ( rac{d}{dx} x^3). The solver understands all three. You don't need to learn special syntax — just describe your problem naturally and Zeretis figures out the rest.

2

Read the steps — don't just look at the answer

Work through each step and make sure you understand the transformation applied before moving to the next. The solver labels every rule it uses — power rule, chain rule, integration by parts, row reduction — so you always know what's happening and why.

3

Close the solver and try it yourself

Now attempt a similar problem without looking. The gap between "I understood the worked example" and "I can do it myself" is where actual learning happens. Zeretis helps you close that gap — not skip it.

Students ask us...

Is using Zeretis cheating?

That depends on how you use it. Copying an answer without reading the steps is missing the point — and honestly probably won't help you in an exam either. Using Zeretis to understand a method, check your working, or study from worked examples is no different from using a textbook or asking a teacher to show you how a problem is done. The steps are the product, not just the answer.

What if I don't know how to write the problem in math notation?

That's exactly what the natural language input is for. Just describe your problem the way you'd say it out loud — "what is the area under the curve y equals x squared from 0 to 3" — and the solver will interpret it. You can always see how it parsed your input before showing the solution, so you can catch any misinterpretations.

What's the difference from a calculator?

A calculator gives you a decimal approximation. Zeretis gives you an exact symbolic result with every step shown. √8 stays as 2√2, fractions stay as fractions, and π stays as π. That means results can be used in further calculations without accumulating rounding errors — and you can actually follow what happened.

Can it handle word problems?

Zeretis is a symbolic math solver — it works on equations, expressions, and integrals. For word problems, you translate the scenario into a mathematical expression yourself, then let the solver work through it. The guide has tips for this. Natural language input helps bridge the gap — you can describe the math part of a word problem in words and the solver handles the computation.

Is it really free?

Yes — 10 problems per month, no credit card required, a free account is required to track usage. If you need more, the unlimited plan is under $4/month on an annual subscription. There are no surprise charges and you can cancel any time.
