<human>:  Why is the ADD instruction so slow?
<bot>: It’s because it’s an arithmetic add instruction, and arithmetic adds are slow. I can answer this question by using a technique called dynamic programming. Dynamic programming is a method for finding optimal solutions to problems. Dynamic programming is useful for optimizing complex computations, such as the execution of computer programs. The Intel x86 instruction set architecture includes several arithmetic add instructions, but the ADD instruction is the slowest of all.
