# What are binary numbers and what are they used for

If you write down the decimal values of each of the digits and then add them up, you have the decimal value of the binary number. In the case of binary 11, there is a 1 in the first position, which equals 1 and then another 1 in the second position, so that equals 2.

As numbers get larger, new digits are added to the left. To determine the value of a digit, count the number of digits to the left of it, and multiply that number times 2. For example, for the digital number , to determine the value of the 1, count the number of digits to the left of the 1 and multiply that number times 2. The total value of binary is 4, since the numbers to the left of the 1 are both 0s. Now you know how to count digital numbers, but how do you add and subtract them?

Binary math is similar to decimal math. Adding binary numbers looks like that in the box to the right above. To add these binary numbers, do this: Start from the right side, just as in ordinary math. Write a 1 down in the solution area. The numbers from decimal 0 through 15 in decimal, binary, octal , and hexadecimal form are listed below.

A bit short for binary digit is the smallest unit of data on a computer; each bit has a single value of either 1 or 0. Binary numbers look strange when they are written out directly.

This is because the digits' weight increases by powers of 2, rather than by powers of In a digital numeral, the digit furthest to the right is the "ones" digit; the next digit to the left is the "twos" digit; next comes the "fours" digit, then the "eights" digit, then the "16s" digit, then the "32s" digit, and so on.

The decimal equivalent of a binary number can be found by summing all the digits. The numbers from decimal 0 through 15 in decimal, binary, octal , and hexadecimal form are listed below.
