messages.content: Rachel's grandfather is 12 x 7 = <<12*7=84>>84 years old.
  Her mother is 84/2 = <<84/2=42>>42 years old.
  Her father is 42 + 5 = <<42+5=47>>47 years old.
  Rachel will be 25 years old in 25 - 12 = <<25-12=13>>13 years.
  Rachel's father will be 47 + 13 = <<47+13=60>>60 years old.
