In binary addition, when you add 1 and 1 the result is 2. ... When this happens, the CPU drops the overflow digit because the computer cannot store it anywhere, and the computer thinks 255 + 1 = 0.

Theoretically, a quantum computer could crack 128-bit encryption almost instantly given the same resources for computing power as any binary system, for example.

As you'll see, Matt Parker uses more than 10,000 dominoes to create a circuit that can take any two four-digit binary numbers and return the five-digit binary sum.
