Learn Calc-Class.
How a problem becomes a model you can change - plus short guides for sharing, classes, and Focus Mode.
The four steps
Every calculator in Calc-Class goes through the same flow.
Add a problem
Type a problem, paste one in, or upload a photo of it - typed problems go straight to the solver, and a photo is read by Claude directly.
Review the math
Confirm the equation, points, variables, or model Calc-Class detected before it becomes a calculator - nothing is created without your review.
Change one thing
Edit any input left changeable and watch the outputs and graph update instantly - nothing is re-sent for interpretation, so it's immediate.
Share the experiment
Share the calculator by link, code, or QR - or assign it straight to a class - no account required for someone else to open it.
Core ideas
What makes a Calc-Class calculator different from a solver.
The structured model
Calc-Class identifies the maths behind your problem - an equation, a shape, a dataset - not just the answer.
What can change
Each model marks the values you're allowed to move, so you can ask "what if" instead of re-typing the problem.
The invariant
The most useful question in maths: after the change, what stayed the same? Calc-Class only claims it when it derives it.
Try an example
Real problems, solved live - pick one to see it become a calculator.
What Calc-Class can build
A real, growing set of problem types - not every math problem yet. When one is ambiguous or unsupported, you'll see that honestly on the review screen, never a silent guess.
Graphing
Points, lines, and quadratics get an actual plotted graph you can read values off of.
Equation solving
Linear and quadratic equations solve completely, with editable coefficients that re-solve live.
Symbolic simplification
Algebraic expressions simplify and expand, with domain restrictions called out explicitly.
Geometry & formula calculators
Shapes, dimensions, area/perimeter/volume, and general formula-based problems (finance, statistics, sequences, and more).
Trigonometry
Right-triangle problems get a labeled diagram; general trig identities solve without one.
Statistics
Mean/median/mode, and linear regression on a data set with a real scatter-and-best-fit-line plot.
Word problems
Translated into a real equation or model where the problem is well-posed enough to do so.
Guides
Short walkthroughs for getting the most out of Calc-Class.
Turn a photo into a model
Photograph a worksheet problem and check what Calc-Class understood before you explore it.
Change one thing well
See live examples of the variable worth moving, and what to look for once it moves.
Working in Focus Mode
Strip the screen back to one model and one question - useful for tests and for concentration.
Publish to Explore
Share a calculator publicly so anyone can open it and make their own copy.
Common questions
Does Calc-Class just give the answer?
Can I use a photo of handwritten work?
What happens when I change a value?
