Answer
Approach
By factoring — find two numbers that multiply to −10 and add to 3.
Type any math problem — Tales solves it step by step, the complete solution your teacher looks for.
An equation, an integral, or a worded problem — the math keyboard helps with ∫, √ and fractions.
The final answer first, then every step with the why — the full solution, not just the answer.
Every solution gets its own link — open it again when you’re reviewing for the quarterly exam, or send it to a classmate stuck on the same item.
Start with the problem you’re most stuck on.
Would you ever doubt what your calculator shows? Tales solves math the same way — with a math engine that computes, not one that guesses.
Every step is real computation
The engine doesn’t write text that sounds right and hope it is. It performs each mathematical operation — the same kind of technology used in professional math software.
Honest when it can’t
Problem types Tales can’t solve yet — like geometry — it tells you straight.
We’ve collected and organized the problem types and exam formats of school math — a bank of 214,000,000 problems that Tales is tested against. The problem you’re stuck on has almost certainly shown up here before.
Everything you solve with symbols and numbers
From Grade 5 fractions, through Gen Math functions and Basic Cal, up to college matrices.
Real exam formats
Multiple-choice, true-or-false and short-answer items — tested on real exam papers, on the topics Tales covers.
Browse solved problems from the bank
From Grade 5 homework to college problems — just type it in. The main areas:
Linear and quadratic equations, systems of equations, inequalities, factoring, simplifying expressions.
Functions — rational, exponential, logarithmic — and the equations they lead to.
Derivatives, integrals, limits, tangent lines, optimization.
Permutations (nPr), combinations (nCr), counting, probability — including conditional probability.
Prime factorization, GCF and LCM, remainders (modulo), fractions and mixed numbers.
Determinants, inverse matrices, systems — plus trigonometry, sequences, and worded problems.
One honest limit: geometry problems that need a figure or a proof aren’t supported yet (see the FAQ). Anything else? Just type it in.
Tales lives inside CalcES, a free online scientific calculator with the same familiar keys as your scical. Finish any calculation there, tap “Solve step by step” under the result, and you get the complete solution of that exact problem — no retyping. CalcES for the answer, Tales for the why.

An answer key gives you the answer. Tales gives you the answer and the complete solution — so the next item, you can solve yourself.
Free — the input box is right at the top of this page. If Tales can’t solve something, it will say so.
