I'm a little embarrassed by this and having a total brain fart.
I understand: (6 * 10^3) + (3 * 10^2) + (5 * 10^1) + (7 * 10^0) = 6000 + 300 + 50 + 7 = 6357 But for some reason I can't get this: (1 * 2^3) is equal to 8. (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11

1*2^3= 1*(2*2*2)= 1*(2*(2*2)). 2*2= 4 so that becomes 1*(2*4). 2*4= 8 so that becomes 1*8= 8.

I was having trouble working out why 2^3=8. As simple as it seems. I haven't done any sort of to the power maths in years and it skipped my mind. But yes, you had answered my question, thank you. But ignoring the 1 in 1 * 2^3 as it was simply telling what binary digit 2^3 was representing.

There are 10 kinds of people in the world. Those who read binary and those who don't.
