You're HOW old?!?!

Today was quite an interesting day in Business class. I learned something that I had always heard about but never exactly wanted to dip toes in because it sounded so complex and difficult. However, I was quite surprised on how fast I picked up on it.
To put it simply, binary code is the language computers speak and process through. In our every day numbers, we go by base of ten numbers (e.g. 10, 100, 1000, 10000) but base of binary code goes up by multiplying 2 (e.g. 1, 2, 4, 8, 16, 32, 64, 128). In binary code, you only use the numbers 1 and 0. What you do is you look at the place value of the base of the binary code and you try to add up to the sum of the number you want.
For example:
Number your trying to make: 45
Place value: 64, 32, 16, 8, 4, 2, 1
>>>>>>>>>>>>1, 0, 1, 1, 0, 1
So to put it into words, I tried to make 45 out of the sum of the numbers in the base value. I don't need 64 to make 45 because it's over the value. I move on to 32, which I need to make 45. Then I go to 16, and I realize I can't make 45 with 32 + 16 because that would be 48 which is over the amount. I do need an 8 because that would bring up the number to 40, which is close to 45. I need a 4 which would make it 44 but I don't need a 2 because it would make it 46 which is over. Finally, I use one which makes it 45.
I was very excited when I finally got it because it was exciting to understand and process. Hopefully, I will find more discoveries like that in Business class.
Goodbye for now,
