Difference between add and multiply node?

Want to know the difference between the add and multiply nodes, problem is when I select an “add” node instead of multiply , my variables start funtioning like a “tick” and dont stop moving in the certain direction

That elementary school level question, one adds numbers, one is multiplying them. So maybe osmething worng with your calculations or programming (order of things you doing).

If you need delta time in tick, delta time is a amount of time between the frames, so you can align variable change in tick event to time insted of frames. If you add delta time on every tick you will simply count time, so if you add delta time to actor position it will move in one direction infinitly, maybe that what are you doing?.

I think you’re going to have to be more specific or provide an example of what you mean
