question: Rachel bought 23 cookies and Janet gave her 42 cookies. The other day her brother ate 44 of those cookies. How many cookies are left for Rachel?
answer: The number of Rachel's cookies is 23 + 42 = <<23+42=65>>65 cookies.
  After her brother’s feast, she was left with 65 – 44 = <<65-44=21>>21 cookies.
