Question

What hex number would you add to 0x58 to set the overflow flag?

Answer 1

To set the overflow flag, add 0xA7 to 0x58.

Step-by-step explanation:

To set the overflow flag, we need to add a number to 0x58 that will result in a result greater than 255 (the maximum value for an 8-bit number). The overflow flag indicates that the result of an arithmetic operation is too large or too small to fit into the destination register.

To calculate the hex number, we subtract 0x58 from the maximum 8-bit value (0xFF). The result is 0xA7. Therefore, adding 0xA7 to 0x58 will set the overflow flag.
