When we are working with Microcontroller or Firmware we often use HEX Values that is Hexadecimal Numbers and we do lot of conversion and calculation like Addition, Subtraction, Multiplication and Division between two HEX Values. To make that process simple and to make you spent more time on your productivity here is the HEX Calculator or Hexadecimal Calculator.

What is HEX Number or Hexadecimal Number?
Hexadecimal numbers are a base of 16 numbering system used in Microcontroller, Assembly language, Core computing and Digital electronics. When we look at Decimal Numbers (Our Daily numbers) it starts with 0 and ends with 9 that is base 10 number system. But HEX or Hexadecimal Number starts with 0 and ends with F totally sixteen numbers from 0. We can write those numbers as,
Decimal Numbers : 0 1 2 3 4 5 6 7 8 9
HEX Numbers : 0 1 2 3 4 5 6 7 8 9 A B C D E F
After 9, decimal increase one digit and counts as 10 11 12 13 14 15 16 17 18 19 20 ….
After F, HEX Number increase one digit and counts as 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 …. Most Microcontrollers and Computers are using HEX numbers because of its easy way to adapt with Binary number system, you may heard of bits 1010 (Four bit), 1010 1011 (Eight bit) like that.
