== Why is this an issue?

The use of operators pairs ( ``++=+++`` or ``++=-++``) where the reversed, single operator was meant (``+++=++`` or ``++-=++``) will compile and run, but not produce the expected results.


This rule raises an issue when ``++=+++`` or ``++=-++`` is used without any spacing between the two operators and when there is at least one whitespace character after.

=== Noncompliant code example

[source,vbnet]
----
Dim target As Integer = -5
Dim num As Integer = 3

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

=== Compliant solution

[source,vbnet]
----
Dim target As Integer = -5
Dim num As Integer = 3

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