Net Amount in RPN Mode

A net amount — that is, the base amount plus or minus the percentage amount —
can be calculated easily with your hp 12c platinum, since the calculator holds the
base amount inside after you calculate a percentage amount. To calculate a net
amount, simply calculate the percentage amount, then press = or -.
Example: You're buying a new car that lists for $23,250. The dealer offers you
a discount of 8%, and the sales tax is 6%. Find the amount the dealer is charging
you, then find the total cost to you, including tax.
