RE: The TAX+ and TAX- Keys
Another alteranative way to calculate [Tax-] even that calculator already have this function or not.

In this case I use Casio Model MS20-UC that alreay have [Tax-] and [Tax+] and with this funcions
can be calculate manually for when user too lazy to change the Tax Rate often so this steps is very helpful.

I'll use the same example problem from the previous post above.

Steps:

480 [+] 9.5 [+/-] [%] display 438.356164384 ≈ 438.36

[-] display 41.6438356164 ≈ 41.64

Remark:

The steps shown above work on certain model.

438.36 [x] 9.5 [%] display 41.6442 [+] display 480.0042

If your calculator calculate percentage this way most likely it will work the same.
