<human>:  Herbert is 10 years younger than Kris. If Kris is 24 years old now, how old will Herbert be next year?
<bot>: How old is Herbert now? ** Herbert is 24 - 10 = <<24-10=14>>14 years old now.
How old will Herbert be next year? ** Thus, Herbert will be 14 + 1 = <<14+1=15>>15 years old next year.
