Coddy Math

Coddy teaches math through hands-on problem solving. You work each step on an interactive board that checks every line, draws graphs by hand, and guides you with immediate feedback. Build a daily habit with streaks, freeze days, and rewards, and validate progress with section certificates you can share on LinkedIn. The math content covers fundamentals, equations, inequalities, systems, graphs, quadratics, exponentials, logarithms, and trigonometry, all free in your browser. View startup
