Trying to read a binary sequence made up of 1s and 0s may seem like an impossible task. With a little logic, it becomes easy to understand. Men easily integrated the 10digit counting system, simply because we have 10 fingers. On the other hand, the computer has only two "fingers": the on and off positions, or 0 and 1, resulting in a twodigit system, the binary system.
Steps
Method 1 of 3: With the exhibitors
Step 1. Choose a binary number you want to convert
We will take for example: 101010.
Step 2. Multiply each binary digit by 2 to the power of its rank
Remember that the binary is read from right to left. The rightmost digit is considered a 0.
Step 3. Sum all the values
Going from right to left:

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
Method 2 of 3: Alternative format with exponents
Step 1. Choose a binary number you want to convert
We will take for example: 101. Here is a slight variation of the previous method. You may find this format easier to understand.
 101 = (1X2) power 2 + (0X2) power 1 + (1X2) power 0
 101 = (2X2) + (0X0) + (1)
 101= 4 + 0 + 1
 101= 5
Note that the 'zero' is not a number, but its value should be noted
Method 3 of 3: cell values
Step 1. Choose a binary number
For example 00101010.
Step 2. Read from right to left
In each box, the values double. So the first digit from the right is 1, the second is a 2, the third is a 4, and so on.
Step 3. Add up the “yes” values
The zeros take the corresponding value, but are not added.
 So, in our example, that gives us: 2 + 8 + 32, for a result of 42.
The 1 is equivalent to a "no", the 2 to a "yes", the 4 to a "no", the 8 to a "yes", the 16 to a "no", the 32 to a "yes", the 64 to a "no" and 128 to a "no". You must add the "yes" and skip the "no". You can stop at the last digit
Step 4. Note that the resulting number can be transformed into a letter or punctuation
In terms of punctuation, the 42 is equivalent to an asterisk (*). Click here for a table
Advice
 The usual calculation rules also work for binary numbers. The rightmost digit increments one by one until it has reached its maximum (from 0 to 1) then the next digit increments one by one and we start from zero.
 The numbers we used today respect positional notation. Suppose we are using integers, the rightmost digit represents ones, the next one tens and then hundreds, and so on. Positional notation for binary numbers begins with one, two, four, eight, etc.
