Whereas conversions change only the displayed number and not the number in
the X–register, arithmetic does alter the number in the X–register.
If the result of an operation cannot be represented in 36 bits, the display shows

and then shows the largest positive or negative number possible.
Example:
Here are some examples of arithmetic in Hexadecimal, Octal, and Binary modes:
