Binary numbers base number

I don't understand. I tried this question twice. I said 1 for the first answer and it said it was wrong, then I tried 0 and it was wrong. It only uses 1 and 0. I don't understand.

Correct binary is a collection of 1 and 0, But in binary it increases the value *2 starting at a Base value of 2.

So.. 1 0 0 1 0 .... Is.... 32 16 8 4 2

The number 1 = 4+32= 36 (you read binary from right to left.) Hope it helps.
