What is `(1111)_(2)+(1001)_(2)-(1010)_(2)` equal to ?A. `(111)_(2)`B. `(1100)_(2)`C. `(1110)_(2)`D. `(1010)_(2)`

Answer» Correct Answer - C
Since, `(1111)_(2)=1xx2^(3)+1xx2^(2)+1xx2^(1)+1xx2^(0)`
`=8+4+2+1=15`
`(1001)_(2)=1xx2^(3)+0xx2^(2)+0xx2^(1)+1xx2^(0)=8+1=9`
`and (1010)_(2)=1xx2^(3)+0xx2^(2)+1xx2^(1)+0xx2^(0)=8+2=10`
`therefore (1111)_(2)+(1001)_(2)-(1010)_(2)=15+9-10=14`
`therefore (14)_(10)=(1110)_(2)`
