The book shows how to add and subtract binary and decimal numbers. However, other numbering systems are also very popular when dealing with computers. The octal (base 8) numbering system is one of these. The following table shows pairs of octal numbers:A Ba. 3174 0522b. 4165 16541) What is the sum of A and B if they represent unsigned 12-bit octal numbers? The result should be written in octal.
