See you there! Right now, let's get to today's answers. A couple of hex reminders....
The letters "A" through "F" represent the decimals 10 - 15, respectively.
The case of the letters doesn't matter. An upper case "A" and a lower case "a" both represent "10".
That said, let's work through each of these exercises:
The hex value a2 means we have 10 ("a") units of 16, and 2 units of 1. 160 + 2 = 162.
B4 gives us 11 ("b") units of 16 and 4 units of 1. 176 + 4 = 180.
3F represents 3 units of 16 and 15 units of 1. 48 + 15 = 63.
1Ac converts to 1 unit of 256, 10 units of 16, and 12 units of 1. 256 + 160 + 12 = 428.
Finally, 2F1 gives us 2 units of 256, 15 units of 16, and 1 unit of 1. 512 + 240 + 1 = 753.
That's it! I'll see you later today with two new videos, and as always, I'll see you on YouTube and Udemy!
