Implementation of multiplier system of processor using sequence system - is it possible?
A "sequential system" is a system that produces the desired result by performing a sequence of tasks. So, for a processor, the task of multiplication can be performed by a sequence of additions.

If you want to calculate 7 x 5, you could start with 0, then add 7 to that number 5 times. The result will be 35, which is the correct answer.

While this is possible, it is not how multiplication is done inside today's processors.
