8,218 PointsSimply put, you start at one, the you double every time. I.E. 1, 2, 4, 8, 16, 32, 64, 128, etc. 1 = 1, 10 = 2 (2 + 0), 11 = 3 (1 +2), 100 = 4 (4 + 0), 101 = 5 (4 + 1), and so on... That is base 2, that's how a computer "understands"... We understand base 10 (0 to 9, so 10 numbers, then we move on)... It works the same way, but 2 instead of 10...

362 Points00000011 = 3 , because 0000001 = (1x1=1) and 00000010 (1x2=2) 1+2 =3
00000111 = 00000100 (1x4=4) + 00000001 = (1x1=1) and 00000010 (1x2=2) = the answer
(my first answer on this forum, let me know if i'm wrong)
