0X3FA is a hexadecimal (hex) number. We can tell it is a hex number because it starts with 0X. Hexadecimal numbers like 0X3FA are not often used in daily life, but we see them used for certain things such as html colors, shortening binary numbers, computer error codes, and math exercises.

The hexadecimal number system has 16 symbols (base 16) instead of the decimal system which has 10 numbers (base 10). The hex symbols are 0 1 2 3 4 5 6 7 8 9 A B C D E F where A=10, B=11, C=12. D=13, E=14, and F=15.

Step 2) Add up all the products you got from Step 1 to get the answer to 0X3FA in decimal.

Here is the math using using the steps above showing you how to convert 0X3FA to decimal.

A × 1 = 10
F × 16 = 240
