Jame has 60 bars of gold.  He uses 10% of them to pay for tax and then loses half of what is left in divorce.  How many gold bars does he have left?
He loses 60*.1=<T>multiply(60, 0.1)=6.0 bars to taxes
That means he has 60-6=<T>subtract(60, 6)=54 bars after taxes
So he has 54/2=<T>divide(54, 2)=27.0 bars after the divorce
