Balance It: The Linear Equations Challenge

An equation is a balance: whatever you do to one side, do to the other. Solve one- and two-step equations, unknowns on both sides and brackets, read gradients and intercepts from straight-line graphs, and crack a pair of simultaneous equations.

What it covers

Algebra & Equations

A topic in Mathematics.

Letters stand in for numbers: simplify expressions, solve equations, read straight-line graphs and master powers, roots and standard form.

Before you start

How it works

  1. 1

    The clock

    You have 20 seconds for each question. When time runs out, the question counts as wrong.

  2. 2

    Your answer

    Your first choice is the one that counts. It is checked straight away, with an explanation where there is one.

  3. 3

    The score

    At the end you see your score and can go back through every question and its answer.

  4. 4

    The XP

    XP scales with your score. Replays earn XP only when you beat your previous best.
