    Dollar Tree bought Family Dollar. Hence them being the same store (it’s not two dollar stores right next to each other).

    Why two signs, idfk. Maybe they were worried people would be upset that their beloved Family Dollar was replaced with Dollar Tree, so they’re easing people in by making it clear they’re the same thing











  • Computers are binary, yeah? So we have to represent fractional numbers with binary, too.

    In decimal, numbers past the decimal point are 10^-1, 10^-2, … etc. In binary, they’re 2^-1, 2^-2, …

    2^-1 is one half, so 0.1 in binary is 0.5 in decimal. 2^-2 is one quarter. 0.11 in binary is 0.75 in decimal. And of course you’ve got 0.01 = 0.25

    The problem comes when representing decimal numbers that don’t have neat binary representations. For instance, 0.1 in decimal is actually a repeating binary number: 0.0001100110011…
