What's going wrong? Your toilet is running all the time? There are simple fixes for this. There's a gasket and a flapper, where they meet is probably the problem. They degrade over time. They make gaskets that slip over the old place, if you can't easily swap it out. You don't have to understand the flush at all to fix toilet issues. If it's leaking, like onto the floor, you have a different problem (tank gasket leaking, or wax ring leaking) If it's something else, just let us know what's happening
