65,535
Using the digits 12279, the largest number that can be represented is 97,221.
If using the compressed format, where a byte holds two decimal digits (because only 4 bits are needed to make nine), so two bytes would be four decimal digits, the largest which is 9999.
31 - it's binary equivalent is 11111
A signed 16 bit number can represent the decimal numbers -32768 to 32767.
Using a decimal, of course. All you need do is move the decimal point two places to the right.
Using the digits 12279, the largest number that can be represented is 97,221.

674
The largest unsigned integer is 26 - 1 = 63, giving the range 0 to 63; The largest signed integer is 25 - 1 = 31, giving the range -32 to 31.
0.9999
If using the compressed format, where a byte holds two decimal digits (because only 4 bits are needed to make nine), so two bytes would be four decimal digits, the largest which is 9999.
The largest Roman numeral number that can be made without using a bar is 3,999, which is represented by the letters MMMCMXCIX.
31 - it's binary equivalent is 11111
A signed 16 bit number can represent the decimal numbers -32768 to 32767.
11b which is 1*2 + 1*1 = 3 would be for two bits. But a byte is 8 bits, so 2 bytes is 16 bits. The largest binary number is [2^16 - 1], which is 65535 (base ten)
The commutative property of addition applies to all real and complex numbers. It has nothing whatsoever to do with the form in which the number is represented: decimal, binary, etc.
Metric numbers are represented using decimal places rather than fractions usually.
