I have never understood the logic of the multiplying function in calculators for this example 9*=81 without inputting 9*9. Is this a product of the logic of the calculator itself or is it specifically coded to do this?

It's a shortcut. It allows you to save time.

I have a calculator that allows short-cuts like that, but not just for multipying.

You can type "9 x →" ("→" is an arrow funtion key)
then, type "1 =" and get 9, type "2 =" and get 18, type "3 =" and get 27, etc.

and

You can type "9 + →"
then, type "1 =" and get 10, type "2 =" and get 11, type "3 =" and get 12, etc.

and

You can type "9 - →"
then, type "1 =" and get 8, type "2 =" and get 7, type "3 =" and get 6, etc.

and

You can type "9 ÷ →"
then, type "1 =" and get 9, type "2 =" and get 4.5, type "3 =" and get 3, etc.

but also

You can type "9 - → →" (to make it "? - 9" instead of "9 - ?")
then, type "1 =" and get -8, type "2 =" and get -7, type "3 =" and get -6, etc.

and

You can type "9 ÷ → →"
then, type "1 =" and get 0.1111..., type "2 =" and get 0.2222..., type "3 =" and get 0.3333..., etc.
