There are 32 bits.
I usually read binary backwards. The bit on the end is 1 (2^0). The second to last is 2 (2^1). The one before that is 4 (2^2). Then 8 (2^3), 16 (2^4), 32 (2^5), ... etc. You multiply the bit (0 or 1) by each of these numbers then add them up. The ones where the bit is 0 will just be 0, so they don't change the number.

000........1010
.............^.^
.............3..1
2^3 + 2^1 = 10, thus it represents 10.
