Help

Tap a tile to select it. Drag or use arrow keys to move it; Shift moves farther. Delete removes it. Ctrl/Cmd + Z undoes a change.

A nearby positive and negative tile of the same term attach in a visible zero pair. Both tiles remain until you cancel pairs. Move one away to separate them; Undo restores them. Different variables or equation sides never cancel together.

Select several lets you tap tiles (or press Space/Enter) to select them. Group combines selected tiles on the same side; dragging or arrow keys then move the group together. Ungroup separates the group. Its label shows the combined expression.

Build accepts whole-number coefficients, parentheses, linear variables and x², up to 60 tiles after simplifying. Squares and rectangles show term types, not a numerical value for x. Moving tiles within one side preserves its value; adding or deleting tiles changes it. This workspace represents expressions. Exploration permits independent editing on each side. Guided solving applies your chosen operation equally to both sides; it does not choose a solution strategy for you.

Guided solving records mathematical steps only. Moves and selections do not add steps. Replay from start and Next math step restore saved models; a new operation from an earlier step starts a new continuation. Equal groups require identical signed whole-tile groups on both sides; fractional/remainder cases are explained without changing your model.

Reset restores the current built problem. Clear makes an empty board. Undo restores changes, including cleared or cancelled tiles.
