== Noncompliant Code Example

----
$target = -5;
$num = 3;

$target =- $num;  // Noncompliant; target = -3. Is that really what's meant?
$target =+ $num; // Noncompliant; target = 3
----

== Compliant Solution

----
$target = -5;
$num = 3;

$target = -$num;  // Compliant; intent to assign inverse value of num is clear
$target += $num;
