What do the numbers in base 8 mean?
The numbers in base eight look just like our normal numbers (except that they never use the symbols 8 or 9), but they don’t mean the same things. You have to think in “eights” to understand them, just as you have to think in “tens” to understand our normal system.
How are steps to the left related in base 8?
Each step to the left involves a multiplication by eight—because we are in base eight. So if there were another digit to the left, we know it would count as “four-thousand-and-ninety-sixes” since that is eight times “five-hundred-and-twelves,” and so on. If you’ve followed everything I’ve done so far, you have hopefully understood a few things.
Is there a difference between base eight and base sixteen?
Just as base ten uses a few symbols that base eight doesn’t need (“8” and “9”), base sixteen uses a few symbols that base ten doesn’t need. These symbols are the first six alphabetic characters. So A represents the number we usually call “ten”; the highest single digit is F which represents our “fifteen.” After that you have to start over.
Can you move from base 10 to base 8?
In fact, moving from Base 10 to Base 8 would hardly give rise to the need for more digits. Two octal digits are almost as precise as two decimal digits. I suppose someone could put my feet to the fire and argue that our senses are capable of dividing into thirds as well.
