Multiply, divide & square root without using arithmetic operators

Question

How can I multiply and divide without using arithmetic operators? I read similar question here but i still have problem to multiply and divide.

Also, how can square root be calculated without using math functions?

Answer 1

if you have addition and negation, as in the highest voted answer to the post you gave, you can use looped additions and subtractions to implement multiplication and division.

As for the square root, just implement Newton's Iteration on the basis of the operations from step 1.
