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 = ?
A Dream
My Dream last night. Last night I had a queer dream. In my dream. I was 40 years old and it was the technological year 2050. The world looked utterly different. Schools were historical pieces of the jigsaw! there was absolutely no traffic, I was seeing scarcely any vehicles on the road and the sound of soaring cars rolled in and soared over my head. Nobody was going to school and virtual learning was the norm. Not even one single dilemma! The city looked forsaken and abandoned, then suddenly I woke up! Do you think the future will have more virtual learning? Will there be flying cars hovering over your head? Please subscribe to get regular updates
