You have to start at the first number on the right. In other words:
When using binary it mainly is saying yes or no, 1 meaning yes, and 0 meaning no.

11001=25

Breakdown:
1=2^4 or 16
1=2^3 or 8
0=none.. If 1 then it would be 2^2 or 4
0=none.. If 1 then it would be 2^1 or 2
1=2^0 or 1

now add the numbers and you get 25.

Each time you go up from your binary code you add 1 to the power.
It's always 2^x.

Just remember this pattern

1 2 4 8 16 32 64 128

then add the numbers up to the 1's that fall in the slots.

So your number 11001 would be 1+2+16 or 19

another example:  101101 would be 1+4+8+32 or 45
