what is n times $100=$25 ?

It isn't $0.25

It is 0.25........

$${\mathtt{0.25}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{25}}$$

$0.25

No happy the answer is not $0.25  That would not make any sense.

It is  great that you have learned to use the calc so well.  I commend you for that .

BUT

You need to have some understanding of what you are doing and of what the answer really is or what it means.

See if you can tell me what the answer really is.
