Step 1 - find the biggest power of 2 less than the number. In this case, 32. Type 1.
Step 2 - subtract it from the number (57 - 32 = 25). Is the next smaller power of 2 less than or equal to that number? (is 16 < 25?) If so, type 1. If not, type 0. In this case, we type 1, and our answer so far is 11.
Step 3 - repeat for successively smaller powers of 2 until you reach 1.
25 - 16 = 9. Next smaller power of 2 is 8. Is 8< 9? yes. Type another 1. 9 - 8 = 1. Next smaller power of 2 is 4. Is 4 less than 1? no. Type 0. Is 2 less than 1? No. Type 0. Is 1 less than/equal to 1? Yes. Type 1. Full answer: 111001
Each digit is a multiple of 2. Starting with the right most digit, you have 2^0, 2^1, 2^2, 2^3, 2^4 and so on and so forth which gives you a numerical value of 1, 2, 4, 8, 16, etc. You then add them up to get the number you need. So for example, 10111 is actually equal to 2^4+2^2+2^1+2^0 (2^3 is not included because there is a zero in that spot). Then just add them up. 16+4+2+1 = 23. For me, it's way easier to work backwards and convert binary to numerical numbers since I don't regularly work with binary so this was particularly challenging for me.
Three billion human lives ended on October 4, 2017. The survivors of the nuclear fire... called the war "Judgment Day." They lived only to face a new nightmare... the war against the machines.
I would suggest that 2 minutes is not long enough. Being 52 and the last binary maths conversion I studied was night on 40 years ago maybe an extra 60 or 90 seconds?
I know how to do it, I'm just not fast enough. I remember in school they taught us by giving us little wooden blocks that were valued, and had representative sizes, of 1, 2, 4 etc. etc and that's how they taught us the binary system.
I thought originally that all computer programs were written in binary code.
I think there needs to be more time, I had 2 left (51 and 54) of which I had almost completed 51, but just ran out of time - I did the others quite quickly too, so I was shocked by how little time I had!

There are two types of people in this world, those who can extrapolate from incomplete data.

Means destroy all humans
Also I’m 13 years old in grade 9 doing grade 10 math in Dawson City, Yukon, Canada
And I did this with 12 seconds to spare and I also haven’t done and binary at all for at least 3 years
64 32 16 8 4 2 1
Under these numbers place a 1 for yes and a 0 for no. e.g:
if your base 10 number is 50
64 32 16 8 4 2 1
0 1 1 0 0 1 0 (32 + 16 + 2 = 50)
