ur right about this, that place is URDU BAZAR. that place is seriously heaven for old books (not that they dont have new books :/) so u may find very very old papers there...

 

[princesszahra]

[Jazib]

Use this http://www.ieeeghn.org/wiki/index.php/B ... inary_Math

i'd rather rely on my calculator
but still, ther's an easy way, which i dnt think is possible to xplain here. :/

 

[Jazib]

aww... this xplains! shud have figured it.
thnx btw.

 

[princesszahra]

now i know another simple way too1

 

[Vnza]

Its just 4 bit conversion, why do you need a calculator for that?
And if you are using Casio ES series, it wont be allowed in the exam. They ill take it away and give you an MS calculator.

 

[Vnza]

And Zahra if you get to know about any site which has old past papers do post it here.

 

[Jazib]

u sure about that ES series?
cuz this is sumthing serious for me...
btw, i still know how to change em manually, just to be on a safe side...

 

[princesszahra]
