How can I multiply and divide using only bit shifting and adding?
... = 21 * 5 (Same as initial expression)
(_2 means base 2)
As you can see, multiplication can be decomposed into adding and shifting and back again. This is also why multiplication takes longer than bit shifts or adding - it's O(n^2) rather than O(n) in the number of bits. R...
