SUMMARY

The discussion clarifies the addition of 8-bit unsigned hexadecimal values, specifically 0x10 + 0xfe, which equals 0x0e (decimal 14). The prefix "0x" denotes hexadecimal notation, and the range for 8-bit unsigned values is from 0 to 255. The conversation emphasizes that the result is influenced by overflow behavior rather than a reset, as demonstrated with additional examples using 16-bit values. The key takeaway is understanding how hexadecimal addition operates within the constraints of 8-bit representation.

PREREQUISITES
  • Understanding of hexadecimal notation and the significance of the "0x" prefix.
  • Knowledge of 8-bit unsigned integer limits and overflow behavior.
  • Familiarity with basic arithmetic operations in different numeral systems.
  • Concept of binary addition and its implications in computing.
NEXT STEPS
  • Study the principles of binary arithmetic and overflow in computing.
  • Learn about hexadecimal to decimal conversion techniques.
  • Explore 16-bit unsigned integer operations and their differences from 8-bit operations.
  • Investigate how different programming languages handle numeric overflows.
USEFUL FOR

Computer science students, software developers, and anyone interested in understanding hexadecimal arithmetic and its applications in programming and digital systems.

Question: With 8-bit unsigned values, 0x10 + 0xfe =
Answer: 0x0e, which is decimal 14.What I know;
The prefix 0x is used in code to indicate that the number is being written in hex. Base 16.
I also am aware that with 8-bit unsigned values it goes from a range of 0 to 255.

Need help with:
Is this working? 10+f = (10+15, the base system is 16 so this is bigger so resets?) 0?
0+e(14)=14, meaning 0x0e I have probably done the working wrong so that's why I need help. Thanks.

Hint: if you use 16bit -
1) 0x10 + 0xfe = 0x10e
2) 0x20 + 0xfe = 0x11e
And in 8 bit:
1) 0x10 + 0xfe = 0x0e
2) 0x20 + 0xfe = 0x1e
So it is more about overflow than reset.
