Day \( 7: 2^{7}=\square \)

On day 7, if you take 2 and raise it to the power of 7, that's like doubling a number seven times. So, \( 2^7 = 128 \). It’s a fun way to see how quickly numbers can grow—just think of a snowball rolling down a hill, picking up more snow with each roll! Not only is this number 128 significant in math, but it also pops up in the world of computing. Computers often use binary code (which is based on powers of 2), and 128 is a common size for data structures in tech, like bytes and arrays. So, next time you use an app or play a video game, remember that magic number powering your experience!
