01 / CALCULATE

Type mathematics, not menu commands.

Start with cos(pi/4), define z=2+3*i, or add two vectors. Press Return to evaluate, or Shift-Return to continue the input.

02 / REUSE

Carry forward exactly what you calculated.

Use named variables, command history, and out(n) references. When you save a chain, its results remain snapshots rather than mysteriously updating after later assignments.

03 / EXPLORE

Visualize, differentiate, and inspect geometric structure.

Go from an expression to its sampled plot, or from a matrix to an index-aware numerical contraction. The app deliberately distinguishes computed components from symbolic geometric derivations still in development.
