This technique in well worth learning, as it can be applied in many
real-world situations, sometimes not even requiring a computer. For
example:

The letter was postmarked on the 18th of May; it was delivered on the
29th of May; how many days was it in transit? You give a $10 note for
an article priced at $6.35; how much change should you get?

HTH,
John
