Hyperoperation is a sequence of operations that extends beyond addition, multiplication, and exponentiation. It starts with basic operations like addition (hyperoperation level 1), multiplication (level 2), and exponentiation (level 3). As the levels increase, the operations become more complex, leading to functions like tetration (level 4) and beyond. Each level of hyperoperation builds on the previous one, allowing for the creation of extremely large numbers. For example, while exponentiation can produce large results, tetration can generate numbers that are incomprehensibly larger, such as 2^2^{2}. This concept is useful in mathematics and computer science for understanding growth rates and computational limits.
