because, N is Natural number
Natural numbers are the counting numbers {1, 2, 3, ...} (

integers) or the whole numbers {0, 1, 2, 3, ...} (


integers).
EQUATION N = -1 could be true if you use an Integer, Z, but with natural number N is not true
You can
put this solution on YOUR website!If N = -1 then -1 = -1, true.
If you're referring to absolute value, since

for all N (as absolute value refers to a magnitude, or distance), then there is no N that satisfies
