How do you read binary code?

When reading binary, remember that each number is represented by a group of 8 digits, which are either 0s or 1s (or, in the case of a binary clock, dark or light dots). You read each group from right to left. Every digit in the group represents 2 to the power of n, with n being that digit’s position in the row. For example, the first digit to the right is 2 to the power of 0 (or 1), while the leftmost digit is 2 to the power of 8 (256). A 1 in a particular position indicates that you read that number, while a 0 means that number is absent. Add up any numbers that are “active” (represented by 1s) to read a binary grouping. For example, 00000010 = 2, while 00000101 = 9.
