Binary

Today in Electronics class, we were learning about binary. Binary is a counting system that only uses two digits, one and two. Binary is also called base 2. We used cards that were black on one side and had the numbers of the 2 times tables on the other. We had to represent numbers that the teacher gave using these cards. After that we used this app to represent numbers in binary. We had to show the numbers 27,15,8 using the app. We also had to show our birth month. Guess which month is my birthday?
