Two 12-bit unsigned binary integers are added together. Before the addition is carried out, the first integer is logically shifted right by 3 places. Prior to this shift, the bit at position 5 (where the least significant bit is at position 0) of this first integer is changed from 1 to 0.
Explain the effect of this change on the final sum.
