Cindy was 5 years old.  Her sister Jan was 2 years older than Cindy.  Their oldest sister Marcia was twice as old as Jan.  Greg was two years older than Marcia.  How old was Greg?
Jan was 2 years older than Cindy who was 5 so 2+5 = <T>add(2, 5)=7 years old
Marica was twice as old as Jan so 2*7 = <T>multiply(2, 7)=14 years old
Greg was 2 years older than Marcia who was 14 so 2+14 = <T>add(2, 14)=16 years old
