**Eisenstein Arithmetic: Express your answers in the form \( x + y\omega \).**

1. \( 2 + 5\omega - 1 - 7\omega = \underline{\hspace{2cm}} \)

2. \( (2 + 3\omega) \cdot (5 - \omega) = \underline{\hspace{4cm}} \)

3. \( (1 - \omega)^5 = \underline{\hspace{2cm}} \)

4. \( 0 + 1\omega + 2\omega^2 + 3\omega^3 + 4\omega^4 + \ldots + 99\omega^{99} = \underline{\hspace{4cm}} \)
