As said it's about superpositions. Normal bits can be set to 0 or 1. Qbits can be in a superpositions of states 0 and 1. So the state of a qbits can be written as a weighted sum of the two states. Now you can do traditional math with this, always could. It's just a physical level difference of the system. There are many bullshit things with quantum computing tho. They are probabilistic in nature and have infinite memory.of the past, for example.
