Way back in the day, we didn’t have base systems! It was uphill both ways, through the snow and blazing heat. When you wanted to count one, you’d write: l When you wanted 5, you’d write lllll And clearly, 1 + 5 = 6 l + lllll = llllll This is the simplest way of counting.
In Roman numerals, two was one, twice. Three was one, thrice: However, they decided they could do better than the old tradition of lines in the sand. For five, we could use V to represent lllll and get something like l + V = Vl Not bad, eh? And of course, there are many more symbols (L, C, M, etc.) you can use. The key point is that V and lllll are...
Another breakthrough was realizing that each numbercan be its own distinct concept. Rather than represent three as a series of ones, give it its own symbol: “3″. Do this from one to nine, and you get the symbols: 1 2 3 4 5 6 7 8 9 The Romans were close, so close, but only gave unique symbols to 5, 10, 50, 100, 1000, etc.
Now clearly, you can’t give everynumber its own symbol. There’s simply too many. But notice one insight about Roman numerals: they use positionof symbols to indicate meaning. IV means “subtract 1 from 5″ and VI means “add 1 to 5″. In our number system, we use position in a similar way. We always addand never subtract. And each position is 10 more t...
Why did we choose to multiply by 10 each time? Most likely because we have 10 fingers. One point to realize is you need enough digits to “fill up” until you hit the next number. Let me demonstrate. If we want to roll the odometer over every 10, so to speak, we need symbols for numbers one through nine; we haven’t reached ten yet. Imagine numbers as...
And what happens when we reach ten? How do we show we want exactly one “ten” and nothing in the “ones” column? We use zero, the number that doesn’t exist. Zero is quite a concept, it’s a placeholder, a blank, a space, and a whole lot more. Suffice it to say, Zero is one of the great inventions of all time. Zero allows us to have an empty placeholde...
Remember that we choseto roll over our odometer every ten. Our counting looks like this: What if we ticked over at 60 when we counted, like we do for seconds and minutes? Everything OK so far, right? Note that we use the colon (:) indicate that we are at a new “digit”. In base 10, each digit can stand on its own.
If we want base 16, we could do something similar: However, we don’t want to write hexadecimal numbers with the colon notation (even though we could). We’d rather cook up separate symbols for 10-15 so we can just write numbers like we’re used to. We’ve run out of numbers (1-9 already used, with 0 as a placeholder) so we need some other symbols. We ...
With me so far? This is pretty cool, right? We can count in any system we want. Also notice that base 16 is more “space efficient” in the sense we can write a number like 11 in a single digit: B. Base 16 really isn’t that different from base 10, we just take longer to fill up.
We’ve seen plenty of base systems, from over-simple unary, to the unwiedly Roman numerals, the steady-going base 10 and the compact base 16. What’s great about binary? In the spirit of keeping things simple, it’s the simplest number system that has the concept of “ticking over”. Unary, where we just write 1, 11, 111… just goes on forever. Binary, w...
In its pure form a simple grouping system is an assignment of special names to the small numbers, the base b, and its powers b2, b3, and so on, up to a power bk large enough to represent all numbers actually required in use.
