255 x 8 < 2000... and, binary is all 0s and 1s. counting to 2000 is 0-9. Also, I did it all on 1 piece of paper. I wrote REALLY small. Takes alot of time. Then drawing lines to seperate rows, then making patterns between the numbers and the lines, as I fit 32 per column, i think, so numbers shifted down 4 lines and over 3 columns per 100.

This was all in HS.
