The discovery of mathematics does not belong to the patent category, patent applications are not accepted, and mathematical patents are not approved. Because mathematics is a basic subject, school education has always been supported by the state, and books on various mathematical knowledge have never been charged to readers as "mathematical patents". Your discovery originated from school education and benefited from previous math books. Once discovered, you pretend to be a strange commodity, and one of them doesn't know the patent. Both of them exaggerated their findings. The three of them want to blackmail the society and really sigh: each has its own strengths, why can't they go hand in hand?
