What does decimal form mean?
 
Can anyone explain to me what this means and it would really help if you could show an example of a integer using the decimal form stated below:

Suppose that the integer n is given in decimal form, where for all i.

I guess I just don't understand the notation and seeing an example will really help.

When you write "316", the "3" means 300, the "1" means 10, and the "6" means 6. This can be written 316 = 3*10^2 + 1*10^1 + 6*10^0.

That's what I thought it was talking about numbers in base 10 but do you have any idea why it is called decimal form? I thought decimals in base 10 would be :

Decimal notation refers to the base 10 notations.For eg:-

156=1*100+5*10+6=1*10^2+5*10^1+6*10^0

As you see the all numbers are multiplying to the 10 which have some power.This is decimal notation.
