# Python 3 program for
# Add two numbers using of bitwise operators
class NumberAddition :
# Add two numbers

# Display given numbers
print("\n [(", a ,") + (", b ,")] ", end = "",sep = "")
# Auxiliary variable which are store the carry bit result
carry = 0
# Executing loop, until b value is not zero
while (b != 0) :
# Get carry bits of a & b
carry = a & b
# Sum of bits of a ^ b
a = a ^ b
# Shift the carry bit by one bit in left side
b = carry << 1
# Display add result
print(" : ", a, end = "")
def main() :
task = NumberAddition()
# Test Case
task.addition(8, 2)
task.addition(5, 3)
task.addition(-3, -5)
if __name__ == "__main__": main()
```
