Algebra you can move.

Learn to solve equations by moving the pieces yourself. Drag terms across the equals sign, combine like terms, and divide to isolate x. Every step preserves the balance.

Keep both sides equal.

x + 3 = 7

Move +3 across the equals sign.

x = 7 − 3

x = 4

Solve it one move at a time

  • Drag a term to the other side of the equation. Its sign changes.
  • Combine like terms to simplify each side.
  • Divide by the coefficient to isolate the variable.
  • Use a hint or undo a move as you learn.

Build your intuition

Five guided lessons introduce balance, negative numbers, coefficients, variables on both sides, and fractional answers. Explanations show why each move works.
