Split-complex numbers, also known as hyperbolic numbers or null numbers, are a type of number that extends the real numbers similarly to how complex numbers extend them. They are defined as numbers of the form: \\\[ z = x + yj \\\] where \\( x \\) and \\( y \\) are real numbers, and \\( j \\) is a unit with the property that \\( j^2 = 1 \\).
