The workspace keeps the graph large. Less common controls live inside expandable sections.

Header, sidebar and graph toolbar

Try it step by step

Choose a sidebar tab for the task you want to do.
Open a section using its chevron. Close it again when you finish to recover space.
Use Collapse sidebar for a wider graph, or Enter focus mode for an uncluttered canvas.

Graph title: Click the title field to name your document. A restored-draft message can be dismissed with its check or close button.
Undo / Redo: Undo document edits such as changing an expression, importing rows or moving an object. Redo reapplies an undone edit. These buttons become unavailable when there is no matching history.
Save / Export / Guide / Quick guide: Save keeps a named browser copy. Export creates a graph image or PDF. Guide opens these chapters; the question-mark button opens the shorter in-app reference.
Back to NUM8ERS: Returns to the NUM8ERS website. Save important work before leaving.
New and Organize: Use + to add content. Organize reveals selection, reordering and folder tools.
Bottom bar: Choose Radians or Degrees, open example expressions, or show the math keyboard.
Graph status: The status bar reports visible plots, points and the current horizontal range. An approximate-contours notice means a relation is drawn from numerical samples.
