Explain in 1-2 sentences how to convert a binary number into a decimal number.
To convert binary to decimal, you multiply each binary digit by 2 raised to its position power (starting from 0 on the right) and add them all together. -
If you are given the binary number 11111111, what decimal number is that?
The decimal number is 255.
