messages.content: If Sierra is currently 30 years old, 10 times her age is 30*10 = <<30*10=300>>300.
  Twenty more than 10 times Sierra's age is 300+20 = 320
  320 is 40 less than ten times Diaz's age so 10 times Diaz's age is 320+40 = 360
  If ten times Diaz's age is 360, Diaz is 360/10 = <<360/10=36>>36 years old.
  Twenty years from now, Diaz will be 20+36 = <<20+36=56>>56 years old.
  #### 56
