The correct answer is: B. 0’s and 1’s have to be properly placed.
Binary numbers are made up of only two digits: 0 and 1. This means that every place in a binary number is worth a power of 2. For example, the binary number 101 is equal to 1 x 2^2 + 0 x 2^1 + 1 x 2^0 = 5.
To count in binary, we start with 0 and then add 1 to get 1. To get the next number, we add 2 to the previous number, which gives us 10. To get the next number, we add 4 to the previous number, which gives us 11. And so on.
As you can see, the places in a binary number are very important. If we were to add 0’s and 1’s to the front of a binary number, it would change the value of the number. For example, the binary number 101 is equal to 5, but the binary number 00101 is equal to 9.
Therefore, binary numbers need more places for counting because the 0’s and 1’s have to be properly placed in order to represent the correct value.
The other options are incorrect for the following reasons:
- Option A: 0’s and 1’s can be added in front of any number, not just binary numbers.
- Option C: Binary numbers are not always big numbers. For example, the binary number 00000001 is equal to 1.
- Option D: The binary base is 2, which is not a small number.
- Option E: None of the above options are correct.
