BINARY AND HEXADECIMAL, Part 1: Binary basics Well, converting gets easy when you know, but at first you have no idea. That's why Mr. Me is here to teach you! |LESSON 1:02:01| Binary time! CDs use binary as well, if you didn't know. 1011010111010001010101110....MALFUNCTION! *game freeze* Binary can be known as "base 2". Well, the word "base" can be replaced with "next column at", so if you do that, you get "next column at 2". The decimal system uses this too, as base 10. Remember in LESSON 1:01, when I said "things beyond the decimal, or "base 10" system"? Well we will use that for our example. In the decimal system, it starts at 0, 1, 2..., 8, 9, 10, 11... Well, if there was more than just 1, 2, 3...., there would be letters! Like 10, 1A, 1B....and even 1-, 1+, 1/! Yeah, you use symbols! Well, binary is like that. Counting the few first numbers are easy. Then it gets harder, at some points. First it goes 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111..... A strategy is, to check all the numbers and to make sure there are no missing numbers, always look if there is a number in between two numbers with just 1s and 0s. for example, 0, 1, 10, 11, 100, 110... did I miss something? Yes, I did! In between 100 and 110. You can find a number in between 100 and 110 with just 1s and 0s! That is 101. It's bigger than 100 and smaller than 110! Well, it's test time! TEST 1. Fill in the missing numbers. 1:01. 10, 11, ___, 101, ___ 1:02. 100, ___, 110, ___, ___ 1:03. 1, 10, __, ___, 101 1:04. 10, __, ___ Too easy? O1:01. 111, ____, 1001, ____ 1011, ____ O1:02. 110, 111, ____, ____ O1:03. 1010, ____, ____, 1101, 1110, ____, 10000, 10001, _____, 10011 Did you answer that last one? Let's see... Cut off the answers! 1:01. 10, 11, 100, 101, 110 1:02. 100, 101, 110, 111, 1000 1:03. 1, 10, 11, 100, 101 1:04. 10, 11, 100 O1:01. 111, 1000, 1001, 1010, 1011, 1100 O1:02. 110, 111, 1000 O1:03. 1010, 1011, 1100, 1101, 1110, 1111, 10000, 10001, 10010, 10011 1 - 3 questions right...were you reading? 4 - 6 questions right...good!
