Say I have 6 rocks and I want to make a nice sign telling people how many rocks I have but I am some strange alien who only has 2 symbols for numbers.

Lets start counting and writing it out using our symbols which don’t exist on a human keyboard so I will use X and Y:

X (we are starting out at zero)

Y (1)

YX ( 2, damn I ran out of symbols so had to make the thing wider)

YY (3, making the thing wider means I can use my old Y position that means 1, 1+2=3 cool)

YXX (4, damn ran out again, gotta make it wider again)

YXY (5, got to add that one again)

YYX (6, I wanted to add a 2 to a 4)

You can abstract over any source of truth, our rocks, and count them in a system of any bases. You have just existed in base-10(symbols are 0-9) your whole life and base-2 (0-1 or X/Y if you want to hammer home symbols only have the meaning we give them) is how computers see the world we made a weird compromise on base-16 for hex (it is about bytes) which we can both sorta understand
