Pretty straightforward. • The next step is to take 2 to the power of whatever place it is, a 2 to the 0, 2 to the 1, all the way up to the largest placeholder. • Then, all we have to do is fill in some mathamatical blanks by completing the exponential 2 problems. • If there is a 1, we keep that number (the two to the exponent solution) and add it to other \\1\\ or \\on\\ numbers. • If it's a 0, we disregard it. • In this video, our number adds up to 75. • ❤️ Support for this channel comes from our friends at Scrimba – the coding platform that's reinvented interactive learning: https://scrimba.com/freecodecamp
