Guys does anyone know about octals and hexals?

I know about octal and hexadecimal

https://en.wikipedia.org/wiki/Octal

https://en.wikipedia.org/wiki/Hexadecimal

 

But it's mathematics, not engineering..

Unless you meant software engineering?

But it's part of computer science area.

Do you mean in metal-graphite compounds (MetalC₆ and MetalC₈)? Would be better to ask in Chemistry in that case. Like Sensei I don't immediately see an Engineering connexion with your question

They are both really just ways for human beings to chunk strings of binary numbers. Your computer will only deal with 0's and 1's.

Actually it was asked in engineering entrance exams thats why I posted it here. And majorly it was for civil engineering, can you guys believe it..

The question was => 137 + 276 = 435, then how much is 731 + 672

Thanks alot Sensei for the links..

It gave me all the details i was looking for..
