Preparing a problem…
Unlimited practice problems in nine topics and three difficulty levels. Each problem is generated backwards from its answer, so the stored answer is correct by construction and your response can be checked exactly — as a fraction, a mixed number or a decimal.
Hints point you towards the method without giving the answer away, and a step-by-step explanation appears once the problem is solved or revealed.
Example
Solve 3x + 4 = 19
→ x = 5 ✓
