The decimal number system and binary number system work the same way; the only difference is what each digit represents (0-9 versus 0/1).

Binary numbers contain only the digits 0 or 1, or bits, where each bit represents a power of two. To convert binary to decimal, multiply each bit by its corresponding power of two and add the results.
