Trying to read a string of binary 1's and 0's can seem a daunting task. However, with a bit of logic we can figure out what they mean. Humans have adapted to use a base ten number system simply because we have ten fingers. Computers, on the other hand (no pun intended), have only two "fingers"--on and off or one and zero. Therefore, the base two number system has been created. [1]

    We'll use this as an example: 101010 .
  2. Watermark wikiHow to Read Binary
    Remember, binary is read from right to left . [2] The rightmost place number being zero.

    Let's go from right to left. [3]
    • 0 × 2 0 = 0
    • 1 × 2 1 = 2
    • 0 × 2 2 = 0
    • 1 × 2 3 = 8
    • 0 × 2 4 = 0
    • 1 × 2 5 = 32
    • Total = 42
  4. Watermark wikiHow to Read Binary
    Let's use 101 . Here is the same method as above, but in a slightly different format. You may find this format easier to understand. [4]
    • 101= (1X2) power of 2 + (0X2) power of 1 + (1X2) power 0
    • 101= (2X2) + (0X0) + (1)
    • 101= 4 + 0 + 1
    • 101= 5
      • The 'zero' is not a number, but its place value must be noted.

    The example we'll use is 00101010 .
  2. Watermark wikiHow to Read Binary
    With each slot, the values are doubled. The first digit from the right has a value of 1, the second is a 2, then a 4, and so on. [5]
  3. Watermark wikiHow to Read Binary
    The zeros are assigned their correlating number, but those numbers are not added.
    • So, in this example, add 2, 8, and 32. The result is 42.
      • There is a 'no' on 1, a 'yes' on 2, a 'no' on 4, a 'yes' on 8, a 'no' on 16, a 'yes' on 32, a 'no' on 64 and a 'no' on 128. "Yes" means to add, "no" is to skip. You can stop at the last one-digit.
  4. Watermark wikiHow to Read Binary
    [6] In addition, you can convert numbers from binary to decimal or convert from decimal to binary .
    • In punctuation marks, the 42 equals an asterisk (*).

  • Question
    How can I turn binary into a sentence?
    Community Answer
    You translate a string of binary code to decimals and then translate the decimals into html code. For example, 111011= 123, 123= { . Write multiple strings of binary code and you'll get a sentence.
  • Question
    Can I learn to read binary if I am frightened of math?
    Community Answer
    You will need some basic understanding of math (addition and multiplication) or a calculator.
  • Question
    How do I add two lines of binary numbers together?
    Community Answer
    It really depends on the method you're using. If you're looking for a sentence conversion, then the computer automatically reads in sets of eight e.g 00111111 (?), 00111101 (=), 01000001 (A) etc. However, the process the computer goes through is much more complicated than that. Essentially, every five digits is equal to either a symbol, number, or letter.

      Tips

      • The numbers we deal with today have a place value. Assuming we are working with whole numbers, the right-most digit is the one's place, the next right-most digit is the ten's place, then hundred's, and so on. The place value for binary numbers go from one's, two's, four's, eight's, and so on. [7]
      • Binary counts just like normal numbers. The rightmost digit increments by one until it cannot increase any more (in this case from 0 to 1) and then increments the next digit to the left by one and starts again at zero.

      About This Article

      Article Summary X

      To read binary, find a number that you want to read, and remember to count the places from right to left. Then, multiply each digit by 2 to the power of its place number. For example, if the 3rd place from the right is a 1, you would multiply 1 by 2 to the power of 3 to get 8. Once you have an answer for each place, add the numbers together from right to left. For example, 101 would translate to the number 9. For tips on using other techniques, like exponents or slot value, read on!
