5 x 2 = 10 halves
2 with 10 remaining110 - 10 = 100 = 50 x 2
20 1 = 1/1 = 10/10, or 10 tenths. 2 x 1 = 2 x 10/10 = 20/10 = 20 tenths
first you forget the 2 is there. then you go : 1/10 x 1/10 x 1/10 x 1/10 x 1/10 x 1/10 = b now make b a 2. 2 x 10 -6 is 0.000002.
262,144 = (2 x 10^5) + (6 x 10^4) + (2 x 10^3) + (1 x 10^2) + (4 x 10^1) + (4 x 10^0)
5 x 2 = 10 halves
2/9 = 0.2222222222 = 2 x 10^-1 + 2 x 10^-2 + 2 x 10^-3 + 2 x 10^-4 + 2 x 10^-5 + 2 x 10^-6 + 2 x 10^-7 + 2 x 10^-8 + 2 x 10^-9 + 2 x 10^-10
1 x 20, 2 x 10, 4 x 5, 5 x 4, 10 x 2, 20 x 1

20 1 = 1/1 = 10/10, or 10 tenths. 2 x 1 = 2 x 10/10 = 20/10 = 20 tenths
10 x 8 + 3 x 2 ie 86
2 x 10^1 x 1 x 10^5 = 2 x 10^6
