MATHSolver v3 Verified symbolically + numerically→

From factoring to
fluid dynamics.

Snip an equation. Scrny shows every step with the rule it applies, then verifies the answer two ways. Built for finals weeks where one wrong sign costs you a grade.

ONE PROBLEM, EVERY STEP

A real solve. Every line, every rule.

This is the worked solution Scrny returns for an integration-by- substitution problem. Not a screenshot of one — the actual output, named rules and all, plus the two-way verification at the bottom.

CALC 201 · INTEGRATION BY SUBSTITUTIONSolver v3 · 2.4s · 4 steps
Given∫ 2x sin(x²) dx
  1. 01Rule · Identify the inner function
    Let u = x²

    Then du = 2x dx, so the 2x dx in the integrand is exactly du.

  2. 02Rule · Rewrite in terms of u
    ∫ sin(u) du
  3. 03Rule · Apply the standard antiderivative
    −cos(u) + C

    From the table: ∫ sin(u) du = −cos(u) + C.

  4. 04Rule · Back-substitute u = x²
    −cos(x²) + C
✓ Verified two ways — both agree
Symbolic d/dx [ −cos(x²) ] = 2x sin(x²) ✓
Numerical At x= 1.5: derivative = 0.532, antideriv-rate = 0.532 ✓
SCREEN · PAPER · SCRIBBLE

Three inputs in. The same verified answer.

Same engine reads them all — screenshot from your tab, photo from your phone, even cursive scratch on graph paper. Below: the verified solution that comes back, identical for any of the three.

/ Screen capture● Input

From any tab.

PDFs, slide decks, browser tabs, video lectures. Pixels in, equation out.

/ Mobile camera● Input

From paper.

Print-outs, textbook pages, whiteboards. Auto-deskew, auto-crop.

/ Handwriting● Input

From scratch.

Pen on tablet, scribble on paper, math notation in any direction.

All three → same verified answer

VS THE FIELD

Six dimensions. One winner.

PhotoMath dominates on speed and the K-12 phone-camera workflow. ChatGPT covers ground in prose. Scrny owns the dimensions that matter when the answer has to be right — named rules, two-way verification, graduate-level reach, and handwriting parity.
