So, the addition of 11011011010 and 010100101 is 11100100111 in binary.

**Why 8 in octal is 10?**

In octal (base-8) numbering, there are only 8 digits available, which are 0, 1, 2, 3, 4, 5, 6, and 7. When you count beyond 7, you need to use a new digit, just as in decimal (base-10) numbering, you use a new digit when you count beyond 9. In octal, the digit 8 is represented as “10” because it’s one group of 8 with 0 remaining.

**What is an illegal octal digit 9 at?**

In octal notation, the valid digits are 0 through 7. Therefore, the digit “9” is considered illegal in octal because it exceeds the maximum digit value allowed in this base. Any digit in a number that is larger than 7 in octal is not valid.

**Why 9 is not allowed in octal number?**

Octal is a base-8 numeral system, which means it uses only 8 distinct digits (0-7). This limitation arises from the nature of octal as a positional numeral system. Each digit’s value is determined by its position within the number and its base, which is 8 in the case of octal.

Allowing the digit “9” in octal would create ambiguity because it would be unclear whether it represents 9 in decimal or a different value in octal. To avoid confusion and maintain consistency within the base-8 system, only the digits 0 through 7 are used in octal notation.

**What is 163.875 base 10 in binary?**
