question: Emily has 4 kids named Amy, Jackson, Corey, and James. Amy is 5 years older than Jackson and 2 years younger than Corey. If James is 10 and is 1 year younger than Corey, how old is Jackson?
answer: James is 10 and 1 year younger than Corey, so Corey is 10 + 1 = <<10+1=11>>11 years old
  Amy is 2 years younger than Corey so is 11 - 2 = 9 years old
  Amy is also 5 years older than Jackson, so Jackson is 9 - 5 = <<9-5=4>>4 years old
