But be aware that if you compute sales tax on individual items, the
total of the taxes you compute may be off by a penny or two from the tax
your receipt shows for the transaction.

These "rounding differences" are inevitable, as a current thread and
many previous threads have discussed. It's mathematics, not any kind of
software error. The only way to prevent them (if you want to prevent
them, as opposed to manually tweaking the amounts) is never to buy
multiple taxable items in the same transaction.
