Peel and Solve is a new algebra method for solving linear equations that helps students undo the last operation first and reduce sign errors.

It includes a free interactive practice tool that walks students step by step through identifying the outermost operation, choosing the correct inverse, and applying it to both sides.

Peel and Solve is designed for maths teachers and GCSE / middle school students who struggle with reverse BIDMAS, keep dividing before subtracting, or “move terms across the equals sign” and break equation balance.

Unlike Onion Skin / backtracking methods that rely on diagrams, Peel and Solve is a text-first decision framework with a clear, repeatable sequence, informed by Cognitive Load Theory (reducing extraneous load).

Is this your classroom?
Does your student keep getting sign errors, undo operations in the wrong order, or forget to do the same thing to both sides? Peel and Solve gives them one consistent procedure they can rehearse on paper or in the interactive tool.
