Please could someone explain to me

X< [X]

[X] means ( Mod X)

Why does this mean X is negative.

I am struggling with this.

X has to be negative because mod X or abs. val. of X is always positive. Therefore, for X to be less than its abs. val., it has to have a negative value.

Let's take example of X= -1
-1 < l-1l
-1 < 1 --> ok

Let's take an example that won't work; when X= 1, positive
1 < l1l
1 < 1 --> wrong!
