Basic Arithmetic Operations For Bases; Negative Expressions - Citizen SR-281N Instruction Manual

In the binary base, the block 1 is displayed immediately after
calculation. Other blocks ( block 2 ~ block 4 ) are displayed by pressing
[ ].

Negative expressions

In binary, octal, and hexadecimal bases, the calculator represents
negative numbers using complement notation.
The complement is the result of subtracting that number from
100000000000000000000000000000000 in that number's base by
pressing [ NEG ] key in non-decimal bases.
