Titik yang berjarak {a} satuan dari {b} adalah $x_1$ dan $x_2$ dimana $x_1<x_2$.

\n

Misalkan $x$ adalah titik yang berjarak {a} satuan dari {b}. Jika diterjemahkan dalam persamaan nilai mutlak, maka $|x-(\\var{b})|=\\var{a}$.

\n

Dari sini, gunakan definisi nilai mutlak untuk menentukan nilai $x$. Yaitu:
$x-(\\var{b})=\\var{a}$ jika $x-(\\var{b})>0$ atau 
$x-(\\var{b})=-\\var{a}$ jika $x-(\\var{b})<0.$
Kemudian, tentukan solusi dari kedua persamaan di atas.

Maka nilai $x_1$ adalah [[0]] dan nilai $x_2$ adalah [[1]].
