First let me show a figure: <div style="text-align:center;"> 200px </div> The graphical association is pretty clear. What, sometimes, is not very obvious, is the fact that <math>(a + b)^2</math> can be seen as literal.

We always assume a number without a sign to be positive. Now textbooks that I had at school and the teachers that I had back then would always say that modulus ''"erases"'' the sign. I always felt that operation to be meaningless because if a number has no sign, does it mean that the number is neither posi...")
