GFG | The same operators are used in java and python |

Let's take a look at some examples to better understand bitwise operators. Note that you typically won't be asked to use bitwise operators to implement addition/multiplication.

## Example - Addition

Try implementing addition using bitwise operators! (Here's an online judge if you want to test it)

Solution

## Example - Multiplication

Now try implementing multiplication using bitwise operators! (I couldn't find an online judge for multiplication, but here's a similar problem: link)
