[Tips and Tricks ] How to turn your calculator off ?

How do you normally turn a calculator like this off ? 

Leave it for a few minutes and it'll turn off automatically ?

or

you just smack all of the key at once with your palm so that it faint off like what I usually do ?

Have you EVER wonder there is actually a simple way to turn calculator off ?!

Well , I honestly never thought there is actually a proper way to turn it off ..

I'm already proud enough for knowing smacking all the keys at once will somehow turn off the calculator *hide away .

Until

.

. 

One of colleagues from my part time job during sem break told me 

and I was so surprised and want to share with all of you 

that 

There's one proper and polite way to turn off calculator

fluently

and here's how it works ! 

To turn a calculator ( for this model ) off. 

you'll only need to 

Press "5" and "6" at once and at the same time press the "ON" button !

and it'll go 

.

.

POOF

OFF !

doubting if it'll work?

Try yourself ! 

It'll also work when you press "x" and "÷" together and press "ON" .

If you are thinking that any two keys plus "ON" will do the same job . 

you're WRONG ! 

Try "9" and "8" with "ON " 

It'll not turn off the calculator . 

Not sure if this method will work on other models' calculator or not . 

Well, 

no harm to give it a try after all 

and if it doesn't work 

try smacking all of the keys at once again .. 

*cough 

And that's it ! 

Do tell me if you guys already know it for a long time

 or

 you only know this after reading this post !

cause I'm not sure that if it's me only that don't know this !

hope you enjoy reading 

with love ,
