5 years ago, a mother was twice as old as her daughter. If the mother is 41 years old now, how old will the daughter be in 3 years?
The mother is 41 years old now, so 5 years ago she was 41-5=<T>subtract(41, 5)=36 years old
At that time the daughter's age was half hers so the daughter was 36/2=<T>divide(36, 2)=18.0 years old
Now (5 years after that time) the daughter is 18+5=23 years old
In 3 years, the daughter will be 23+3=<T>add(23, 3)=26 years old
