When using a basic handheld calculator that has a % key, what would be the
normal key sequence to calculate n+12.5% where n is any number?

On the calculator I have:
n x 12.5 % + =

Although personally I would normally do n x 1.125 =

Thanks Chris.
On the program that I am using, ESBCalc, your first sequence produces an
"Error" display.
The latest Karenware calculator program doesn't have a % key.
Unbelievable.....
It will be interesting to hear from others as well.

It may not like the + = sequence.

If its GST youre trying to work out
n/8 + n =
If youre working out much GST you just paid
n/9=

Most basically, I think:

n x 12.5 = / 100 = + =

[or]

n x 9 = / 8 =

[or]

n x 1.125 =

AFAIK the % key completes the calculation then multiplies the answer by 100.
There is probably no % key which is similar to a 'sign change' key.
