Questions, answered
How do I solve a problem?
Type your answer and click Submit. CalcForge checks whether it is mathematically equivalent to the correct answer, so 1/2 and 0.5 both count.
What are Power-Ups?
Skip, Super Hint, and Graph Overlay. Free accounts get a few each day; Premium unlocks unlimited.
How does grading work?
A symbolic math engine (SymPy) compares your answer to the reference. It is never a string match, so different correct forms are accepted.
What if I get stuck?
Reveal a hint (each one costs a little XP), or open the step-by-step solution. Viewing the solution forfeits points for that attempt, so it is always your choice.
