Post an equation, and the next poster must solve it. When that poster solve it, they must counter it with another equation. Work can be shown, but for ease of reading, one can simply post an answer.

If know one answers the equation in 24 hours, or 3 people answer incorrectly, the poster of the equation is granted one point(only if they post the correct answer). The one who answers an equation correctly is also granted one point.Â
In addition, after the 3 people answer incorrectly, or 24 hours pass, the poster of the equation must post a new problem.
