Kiarra is twice as old as Bea. Job is 3 times older than Bea. Figaro is 7 years older than Job. Harry is half as old as Figaro. If Kiarra is 30, how old is Harry?
Bea is 30 / 2 = <T>divide(30, 2)=15.0 years old
Job is 15 * 3 = <T>multiply(15, 3)=45 years old
Figaro is 45 + 7 = <T>add(45, 7)=52 years old
Harry is 52 / 2 = <T>divide(52, 2)=26.0 years old
