👉 In mathematics, a "basepoint" is an element of a field or algebraic structure that has the property that it is its own additive identity. This means that any number can be added to the basepoint and the result will also be equal to the original number. For example, in the complex numbers (Z), the basepoint at 0 is the number i, which satisfies the equation i^2 = -1. Similarly, in the field of real numbers (R), the base
