3FAQ
What is the difference between binary and decimal?
Binary is a base-2 number system using only 0 and 1; decimal is base-10 using 0-9. Computers internally use binary.
How do I manually convert binary to decimal?
Starting from the rightmost digit, multiply each digit by 2 raised to a power (starting from 0), then sum all results. For example, 1011 = 1*2^3 + 0*2^2 + 1*2^1 + 1*2^0 = 11.
