Convert these numbers from binary into normal numbers 1) 10011 = ? 2) 1100111 = ? 3) 111011 = ? 4) 10001 = ?  5) 111 = ? 6) 1101 = ? 7) 101010 =?  8) 110 = ? Perform the operation then convert your answer to binary. (Hint: not all operations are the same as normal numbers!) Also you will need to tell me the binary answer and the normal number answer once you converted it. 10001 + 1001 = ? 101 x 11 = ? 1101 - 100 = ? 10011 + 111 = ?
