👉 In mathematics, an extended number is a complex number that can be constructed from another complex number and its imaginary part. This means that it has both real and imaginary parts. For example: - 3 + 4i is an extended number because it can be expressed as (3+0i) + (4+0i) = (7i) - -2 + 5i is also an extended number because it can be expressed as (-2-0i) + (5
