First number:11110010 Here first MSB(Most Significant Bit)is 1. So the number is negative number. 1's complement of first number:00001101 2's complement of first number:00001110 Decimal number corespond to 00001110 is 14. here the number is negative. so -14. In the same way find second number that is -13 so the sum is -27 |
