This math doesn't make sense

Gross income : $271.38

Trade Route    :    58.23

Taxes (paid by citizens to me I assume) :  33%

Expenses        :  $122.77

Now from my math this comes out to a large positive number  Excluding the Tax income I should have an income of $206.84 minimum and taxes makes much more.

Instead I have an income of -14.00. EXCUSE ME but how does that number come about????
