how the computer multiplies or divides?

Question

do I know that when adding, the computer adds the bits with the help of some gates, and could someone help with the multiplication division?

Answer 1

Better search on Google for "How an ALU works". There is plenty of information available.

Answer 3

This is how I think computer calculates division, I think it os based on testing results with *.

If:
numerator / denominator = quotient
Then:
denominator * quotient = numerator

Computer could use this information to calculate the division result.

Computer would start with 4 variables:

nominator,
denominator,
quotient = 0
counter = 1

Computer would start a loop with undefined break.

In each iteration it would compare the nominator to this expressiln:
quotient + counter * denominator

If the nominator is equal to the expression, this will be added to the quotient:
counter * denominator

and the loop would be broken.

If the nominator is less than the expression, the counter would be divided by 2 using >> and the loop would continue from the next iteration.

If the nominator is greater than the expression this would be added to the quotient:
counter * denominator
after that counter would be multiplied by 2 and loop continues to the next iteration.

Answer 4

What is an ALU?, sorry just i am a student, and i now sutdy at home

Answer 5

ALU stands for "arithmetic logic unit".
