$color(blue)(=> 3n - 3$

$n-{1 - [n - (1 - n) - 1]}$

$=> n -1 + [n - (1 - n) - 1], color(red)("Removing {} bracket"$

$=> n - 1+ n - (1-n) -1, color(red)("Removing [] bracket"$

$=> n - 1 + n -1 + n - 1, color(red)("Removing () bracket"$

$=> n + n + n -1 -1 -1, color(red)("Rearranging Like terms"$

$color(blue)(=> 3n - 3$

What is n-{1-[n-(1-n)-1]}n-{1-[n-(1-n)-1]}?
