Ternary logic is like a type of math that uses three values for calculations - true, false, and unknown. This can be used to solve problems that need more than two different answers. For example, let's say you go outside and you want to know whether it's sunny, rainy, or cloudy. With ternary logic, you could use a three-value calculation to decide the answer. If it's sunny, the calculation would be true, if it's rainy, it would be false, and if it's cloudy it would be unknown. This same logic can be used to solve all kinds of problems.
