At this point, everyone appriciates binary. . !

Here's the most confusing thing you'll ever hear. Hexadecimals!! But gladly, its not so confusing after today's class. We spent all of today's class reviewing hexadecimals, and touching upon a little bit of binary as well. The only reason I'm saying that hexadecimals are confusing is because it not only requirs numbers, but letters too. But once you listen very carefully, and actually try to understand, rather than giving up, its fairly easy to grasp the context. Of course today wasn't our first class on learning hexadecimals, but I feel that a review always helps the proccess of understanding. So here's a quick review, and everything we talked about in class.
As you know, hexadecimals is base 16. Of course, in grade 2, we all learned this consept but with base 10, and a lot easier information. The reason i reflect back on grade 2 is because we have learned that there is always a ones place and a tens place. You can only go up to nine on the ones place, then you need to start carrying into the next column, which is the tens. Hexadecimals is similar. You go up to 9, and then when you get to 10, you also carry the one to the next column. The only difference here is that you cant have two digit numbers in one place value. So you can't write 10 under the tens value, because that would not work. So instead of writting a ten, you would start with the letter of the alphabet and work your way down. So you would write ''A'' under 16, and any number lower than 10 under the ones, depending on what number you are trying to get. So for example, if you wanted to make the number164, you would have to think how many 16's are in 164. In this case, there are ten 16's in 164. So you would put an ''A'' under 16, giving you 160. And you put place a 4 under the ones column, making 164!
Its very easy once you practice it a few times. Although, keep in mind that the letters only go up to ''F'', which is 15, because that is the highest value.
Another thing we quickly reviewed today was photoshop. We explored some photoshop, and got a general idea. Though we still have a lot to cover in the next while. We are soon going to learn how to fix pictures like their color, shapes, and so much more. But a cool fact that we learned today is that the hexadecimal code for colors can only go up to six digits. This is because of the RGB pixels. (red, green, blue) In every color there is some red, some gree, and some blue. Now each of them more or less, but they are always there, unless you want an absolute color. I wont get into a lot of detail for now untill we learn more.
So see you next time.
Bye.
