## Why is this an issue?

Using operator pairs (`=+` or `=-`) that look like reversed single operators (`+=` or `-=`) is confusing. They compile and run but do not produce the same result as their mirrored counterpart.

    Dim target As Integer = -5
    Dim num As Integer = 3

    target =- num ' Noncompliant: target = -3. Is that the intended behavior?
    target =+ num ' Noncompliant: target = 3

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

Replace the operators with a single one if that is the intention

    Dim num As Integer = 3

    target -= num  ' target = -8

Or fix the spacing to avoid confusion

    Dim num As Integer = 3

    target = -num  // target = -3
